While I think white bias is still an issue - seems like this is what you're pointing at exclusively, right? - I think a possibly bigger issue here - and the answer you're looking for - is that Obama was a classy face for progressives to look at when these government encroachments (and - in many cases - outright killings) came up. Now that Trump is the face of this disease, there is no pretense. The face lines up with the actions. This allows everyone to freely mobilize on their issues without feeling like they are stepping on toes. Classy, wingtip toes, that is. Now, I'm not a Trump hater - I don't think he's Hitler. In fact, I do thank him - he did drop the pretense on his own. But I also am enjoying seeing America radicalized in a way that I hoped would happen with the Snowden disclosures fell.
