I've been giving pretty cogent arguments as to why your ideas are illogical and rooted in xenophobia and yes, (gasp) racism. How dare I!? You poor thing
Look, maybe this will clear things up. I (and maybe I can speak for "the left" here) don't think that holding racist beliefs is *evil*. I think it's part of being an imperfect human who absorbs their environment. I bring up the concept of racism not to "cancel" or insult someone but to hold a mirror to their beliefs and try to get them to reflect critically. The problem is that you see it as ad-hominem. It's not.
Racism is an issue of prejudice yes, but it's also in large part an issue of policy and social organizahtion (systemic stuff)
