Trying to cast the black bloc in terms you can relate to misses the point of the black bloc. They’re anarchists. They’re not on anyone’s side except the side of anarchy. They protested President Obama. They’re protesting Trump.
They don’t wear masks to avoid persecution — they wear masks to avoid prosecution. They’re there to do as much damage and merge back into the chaos. Your organization schemes won’t apply to them and they won’t stop just because you pen an article. Their agenda is theirs alone — and no matter how much we dislike their antics, they’re not going to quit.
