I don't know much about him (yet; I'm intrigued, though), but I know he's declared himself as a Democrat, a Republican and an independent at different times, so he's not a devout Democrat. I read somewhere that he said no candidate could win the presidency outside of the two major parties, so I assume he's aligned with them for purely strategic reasons. Apparently the Democrats are okay with it since Bernie Sanders is doing the same thing.

I don't think Bloomberg is the garden variety deplatforming, canceling Democrat, but has to tread carefully to have a chance at winning the presidency.

As I said earlier, this report on Bloomberg's thoughts actually are encouraging, since, like you (I assume), I can't stand the politically-correct nonsense of the far left. I don't think Bloomberg really supports it either.
