Labeling an entire group of people “the problem,” based on a superficial demographic trait is prejudiced and unhelpful. You often alienate the very people you want help from. Rather than using a superficial trait that has nothing inherently to do with the problem, target the problem itself: the problematic ideology.
I don’t care to debate this, tbh. If you really think white people are the problem you’re just being racist too, and I have no patience for that.
