It isn't necessarily the colour of their skin that I personally worry about. Its their countries of origin...Actually, its only been recently that more Mexican came into the US than left to go back to Mexico.
Prior to 2000 there was a massive influx. For the first decade and a half of this century, more Mexicans left the US than came in. Since the turn of the century there has been a rough parity of between those entering and leaving. The US has not been overrun by brown people in the last two decades.
I'm not saying that a country shouldn't do something to stop illegal immigration, it clearly should, but this has become a racial dog whistle issue on the part of certain members of US society well beyond the issue that it is.
How the heck does a dirt poor Somali get himself to South America, then up through Mexico?
Or an Afghan? Most homes had one working light bulb, some not even that...some would trade random things they found as currency.
None of them had the financial means to fill a gas tank, so flying across the world while having enough means to feed themselves and get to the southern US border has me raising an eyebrow...
How are these folks getting enough money to travel like this? Who is paying them, and who's paying for them? And the big question is why?
Like I said, all its going to take is one S-vest at a shopping mall or a busy Wal-Mart, and the US economy is going to be thrown into chaos.
Or one high profile murder where an American is murdered by a migrant receiving the $1000 UBI, and you'll have protests all over again.
I don't want to sound alarmist, but I don't see this ending well...
I see this as a huge security issue, and a quality of life issue. Not a racial issue.
