I’m not American and I’ve always found it fascinating how a part of the American population defends the existence of illegal immigrants in American soil. It’s crazy.
It's a country founded by immigrants and for much of its history it welcomed them (with some significant caveats). The assertion that America is only for people who are already here is both radical and relatively recent. That's what's crazy.
Well, to be fair, most immigration policy can be traced to blatantly racist policies, for instance against people of chinese descent.
