Comments like this are unhelpful for finding the truth. The world would be nice if things aligned on a clear good vs evil axis, “the other side is just evil of course!” but they don’t.

I know people on both sides of the political spectrum and there’s pain and confusion across society. Perhaps one side has more power in this moment and more harmful impact but making sweeping claims, "it’s all racism" is what makes a group feel unheard and angry.

Stating the truth is unhelpful for finding it?

It is because of racism. People were told about the invasion coming over the border, and that Trump would stop it, and they voted for Trump.
