I find walking with signs, holding their own rallies (seperate from another's permitted  rallies) and having press conferences excellent. That is the true American spirit and we are fortunate to be able to do that. 

I do not find refusals to vacate a building owned by another, blocking traffic, screaming in people's faces, demanding speakers be banned, or showing up with faces hidden  and getting physical or vandalizing appropriate at all. In fact the two latter ones are criminal behavior.

I say that for all sides btw. But the ones making the news lately with aggressive behaviors have been the actual self-proclaimed neo-Nazi's (like the Skinheads or the prison-generated White Supremacists) the aggressive self-identified  BLM members and many of the Antifa (which they are world wide, not just here.)
