No, he's saying the people claiming the US is a "racist hellhole" don't know what a racist hellhole actually is.

OK, but "these woke folks" don't say that we've come a long way from the 1950s or 1850s. They sound like we're still a nation that has legal slavery.

I'm not saying that they should settle for where we are now. No, we need people who keep pushing us to make good on the check that Jefferson wrote when he said that "all men are created equal". But when you talk as if we've made no progress, people who are at least nominally on your side are going to start tuning you out. That may not be good strategy...
