I kinda have to question the motivations of a civil rights group deciding to march in Selma of all places. The only point of doing that, as far as I can see, is to start a fight. Everybody with even a minimum of political awareness knows how well that's going to go over.

There's a fine line between speaking out to your opponents directly to their faces (which is perfectly acceptable) and sticking your thumb in their eye. It looks like everybody showed up to this thing itching to throw down.

If you disallow people from protesting just because of their stupid/ignorant/evil ideology, it's only a matter of time until it's you. You should be embarrassed to say what you just did. Would these alt-right shits give you the opportunity to protest in a heavily alt-right city? No they wouldn't. Don't turn into the thing you hate trying to destroy the thing you hate. If you truly believe that liberal ideology is better, which I do, then you should believe those ideas will win out in a free environment.

How many white counter protest have violently attacked civil rights protests in American history alone? Too many, and it was a facist thing to do then as it is now.
