It is reasonable (but not particularly productive) to discuss whether Trump's policies are fundamentally racist or not. It is simply absurd to say, or imply, that borders are inherently wrong.
Perhaps, though it's worth asking what people think would be so awful about Open Borders (TM). Is it just that people who SHOULDN'T BE HERE might be here? Is that the fundamental argument?
I'd be all for open borders if there was no welfare in this country. However, if your policy is that there are minimal obstacles to entering the country, and that upon entering you become eligible for food stamps, Medicare/Medicaid, Social Security, free college, free health care, or any of the other free stuff Democrats are promising, then you'll incentivize mass immigration into an already bloated system that won't be able to support the new arrivals. It doesn't take a genius to realize that the American welfare system can't also support the entire population of Central America.
Then again, of course, there's the fact that open borders would flood the country with cheap labor, driving down wages for native-born Americans. Even if you set a minimum wage, you have millions of migrants working off-the-books for companies that can pay them a quarter of what Americans would demand. Open borders is just another race-to-the-bottom policy that will further impoverish American workers. It's a Koch Brothers wet dream. And the fact that the corporate masters who control the Democratic Party have conned their followers into thinking that this is some kind of "social justice" issue speaks volumes to how gullible Millennial Twitter activists are, and how detached the party has become from its roots in organized labor.
