I'll bite.
It's not bad or racist to enforce immigration laws. Very few people in America support legitimately open borders and I do not either; the only ones that do are purist libertarians. Faux concern for these issues however is a hammer used by bad and, yes, racist people in order to batter people who are overwhelmingly poorer and non-white.
There is no evidence that a physical wall is a necessary investment and there are zero lives improved by separating children from their families as a "deterrent" during a massive humanitarian crisis.
A decade ago, I used to think that the Republican concern over illegal immigration (which is absolutely a legitimate concern), was truly out of concern for those exploited by the system and out of concern for the American worker. I thought that those calling this concern as "anti immigrant" were being disingenuous. Of course, that was before I realized people like Stephen Miller are really saying the quiet part loud these days.
