Speaking as an immigrant myself, immigration without assimilation is worthy of scorn. I have it relatively easy living in Japan where people are easygoing, but as of late that patience is being tested. I've seen videos of people getting pissed off at Kurdish immigrants from Turkey who won't keep their head down and blend in, and instead are annoying the locals. I have no idea what function they serve in society here, but I say send them back.

Likewise, I'm tired of Americans who come here and think, "Oh boy, now I get to complain about being discriminated against like an annoying black guy because that's so cool." If all they do is bitch about the host culture, they should just go back home and this place isn't for them.
