Is Black Lives Matter a "hate group?" What about Blue Lives Matter? What about an anti-BML group? Who decides? And once they're a hate group, according to you everything they publish is automatically considered "hate speech" and therefore banned. Seems overly broad.
Honestly yelling "it is just obvious" is very naive and unworkable. People have tried for years to come up with black and white definitions of these things and they've all failed. It often boils down to "when I see it, I know it" but that varies per individual.
