As someone who's never found its place in the world, I think I can understand a thing or two about this matter.
Just looking at the middle east you can find a lot of trouble concerning land, the Kurds and the Jews want to have a home and it's hard to just take someone's land away. But why do those people matter and need to have a place to live while the rest of the world is heavily mixed by mass immigration?
Of course, political advantage.
But among us common people I think we can talk about the matter without involving left and right and all that messy stuff.
Supporting heavy immigration for the sake of "diversity" will end diversity because everyone will just live under the same culture - some people try to disprove that saying that mixing doesn't take away culture, but I think we all know that's a load of bullshit.
Culture is heavily influenced by geography and historical events, if we all lived in america from the start we wouldn't have different clothings and food. Even the time native americans spent alone in the land gave them different cultures, not to mention what came through their countless wars - despite the lack of basic technology such as the wheel.
Where I live when you talk about scandinavia someone will always bring up cod because of the cold waters (I think it's more of a portuguese food, but whatever I guess), and how people are blond with blue eyes. Now imagine if Norway was a hot desert. They would need different clothing to protect them from the sun, different food because you don't have cold water in the desert, they might never have viking ships or viking mythology.
But why do people need a home?
As humans we like to be among others who are similar to us, we like to be normal. A lot of feminists might say we should all be different and wage war against the norm, but again, BS. Being different sucks, it sucks really bad. When you're different you start with a disadvantage, you have to overcome your difference before you can do something meaningful with your life. While normal people just start from square 0, you start from -10.
Now, that's not to say we should be banishing gays and drowning babies with down syndrome, we can handle difference nowadays because of the quantity of resources we have and the lack of wars - but we shouldn't be commemorating difference, we should be commemorating freedom.
Now imagine there was a piece of land for gays where 90% of the population is homosexual and there are no problems with marriage laws or crazy religious people. If a gay person is unhappy living somewhere, they can always go back to that land - it's their home. And let's say they use the more commonly known gay culture, so everything there is colorful and they have their own clothing, architecture and festivals. Of course, gay people aren't a race so they can't have that, but when you think of this home idea, this safe haven, doesn't it sound nice?
If you like diversity, you should hate race mixing. It may sound like a great thing that white people are accepting black people and having babies with them, but it's actually really, really bad. I know you always hear right wing supporters telling you to think of it the other way around, but really, think of it if it was the other way around - white people going to africa, having babies with black people and turning the population white until there's not a single black person left.
Now how about we rarely ever mix races and all races remain mostly intact?
Sounds horrible to the politically correct people, because someone told you mixing is good and progress and whatever but here's the thing - if you're the baby and you're born mixed, you go to school and your friends ask you "Are you black or white?" how do you know? How do you find your identity? You've suddenly just lost your home, you can't go to a land where you are the norm anymore, because you are a mix. Can you imagine how unsettling this can be?
Now imagine this same kid looking at their white mom and their black dad and how confused they might become. Children don't understand political correctness, they will see their friend being black with both parents also being black and he won't understand why he has to be different - again, being different sucks.
(Note: on the africa example I overlook the differences between different colored people in africa and their tribes, and how usually the black genes pass more often to the phenotype)
You probably have seen the image above over and over again being used to defend equality or some argument against racism. Well, other than the gay/straight and atheist/catholic that image is bullshit.
You see, one of the amazing things about having different races is we are truly different and we get to see how humans can have different traits, different characteristics and different bone structures.
You can't celebrate diversity and say we're all the same, that's just not how it works.
Ask any scientist, doctor or archaeologist who works with bones, they know the race from just looking at it.
While the image probably has the good intention of saying we shouldn't be judged by our appearances, and I completely agree with that, it makes it seem like we are all the same and that is why I hate it.
Asians are short, certain types of black people are tall and slender, certain white people are tall, south americans are short. Asians have straight black hair, black people have wool-like hair. White people have a more square-shaped skull, black people have a more prominent 'mouth area'. Skin, eyes, noses...
And that's all great!
If you've ever created a D&D character you know how interesting just describing your character's anatomy can be. How different elves can be from dwarves and how fun it can be to describe a bullywug.
Mixing everyone together into a weird human blend is almost just as bad as Hitler's arian race, our freedom comes from our differences.
I'm not saying we should have harsh laws against intersexual marriage or any kind of crazy thing like that, but we all know how the mixing is being pushed into people. To the point white girls will have sex with black men just to prove they're not racist - do you see how ridiculous that sounds?
You want to prove you're not racist? Then support the existence of black families. And white families, and asian families. Support the idea of having children that people have been fighting so hard against and let everyone prosper among their own people.
Now go ahead, ignore all I said, call me a nazi racist white scum and share it with all your left wing communism supporting friends.
