I am also very aware of him and have watched him a lot. There are some differences between him and TBA I think.
1. Dr. Richey seems to be part of the Democratic party crowd. I don't think you will ever hear him say 'don't vote unless its for tangibles' I think.
2. I also think as some people say, he's 'progressive' as in white progressive in mindset. If you are trans, latino, etc, fight for them. His focus seems to be 100 percent black related but if he's with TYT, presumably he agrees with them on protecting trans, immigrants, etc.
3. I also don't think I've heard him say or thinks reparations are a solution. Maybe he does, but I've never seen any evidence of it. My guess is he isn't ten toes down about it if he is at all.
I'd say he's closer to Professor Black Truth in his platform. TBA is way more than that. I haven't heard Dr. Richey talk about solutions. I think he's a good guy. Anyone exposing racism towards blacks publicly on their platform helps the cause. But I personally wouldn't put him anywhere near TBA, PBT's level until I hear him a. specifically call out white supremacy in the same manner they do and b. mention reparations for FBAs.
That doesn't mean he's not good for us, just means he's not at that level.
