The USA currently allows about 1 million LEGAL immigrants each year. And based on country of origin, about 90% of them are black and brown.
And Republicans are generally fine with that. So no, Republicans aren't racists. You rarely hear them complain about legal immigration, other than maybe we should let more people in on merit and less on chain migration.
But we gotta shut down the massive illegal immigration. Not just catch and return them, but prevent them from even entering. We need to build a barrier of some sort. A Big Beautiful Wall with a moat and alligators in the moat, or whatever will keep them from coming in. If it's numerous barriers and guard towers every mile or whatever, then that's what it takes.
And yes, I know about 50% come in on Visas and overstay them. Maybe we need to restrict that, or put some sort of safeguard on their return, like requiring BAIL that is confiscated if they do not return.
