You don’t even need an objective reason (not that there aren’t some) to want to live in a completely/mostly homogenous society made up of your own people.
If you prefer your own people, the way they look, the way they think and feel, that’s reason enough.
Obviously some of the psychological differences between the races are environmental, and some are genetic, it’s a combination, it can’t be all one or the other.
And some cultural and familial differences are so deeply rooted, they might as well be genetic, it’s almost impossible to get rid of them, unless the kid of x race were to lose their parents and be adopted by parents of another race, from a different neighborhood or part of the country, and even then they’d still be exposed to their races culture via the MSM, and probably identify with and gravitate towards some or all of it, because humans naturally tend to be like that, tribal.
I don’t know, there’s nothing necessarily wrong with wanting to preserve, or mix your race, I think it’s up to every individual and society to decide for themselves individually and democratically, but if most people would be happier with less or no immigration, I think it’s wrong for politicians to force mass immigration on them, and of course we know the real reasons why they’re forcing it on us, they’re financial at best, and anti-European sentiment at worst, not humanitarian, the politicians demonstrably don’t give a fuck about humanity, they’re too busy filling their own pockets.
Preferring and wanting to preserve your own race is not hate, so long as it doesn’t lead to violence or abuse of others, otherwise, Israel and Japan, who don’t let in foreigners, except for to visit, are hateful countries.
It’s just a preference, it shouldn’t be tabboo, we need to openly discuss the subjective, and objective issues regarding immigration openly instead of having a chidish complex about it.
And some cultures/races are more compatible with ours than others, obviously.
