I do not know how many white supremacists there are, maybe a few thousand or even more. But out of a population of 330 million, they don't make any difference. I am unaware of any GOP proposed legislation that is in the best interests of the white supremacists that isn't also in the best interests of everyone else. So why are they getting so much attention?
Answer: politics. The Left constantly tries to pin the evil deeds of those few onto every person on the Right. It's all about demagoguery, which these days is standard politics. Do you hear the media talking about inflation and the economy? You know, the stuff that really matters to most of us that ain't wealthy? Are they talking about the student loan forgiveness for households making up to $250,000? No, they're talking about white supremacy and racism, like it's any different now than it was when Obama was in office. It's called diverting attention away from what matters to what doesn't for political reasons.
