One can criticize both groups and still not be neutral. As I have stated, I do not like the neo nazis (not sure if all the original protesters are that or if only a few of them are, either way, they all seem quite unlikable).
What I have really been against is the "just arrest people for being seen in a group" which is what my comment was really replying to. Asking for discriminatory laws like this is backwards, harking back to when there were discriminatory laws against people with black skin. Although I know this is not what you were replying to, this is just to show why I made the comment in the first place. Also I seem to be being called a libertarian just for disagreeing with what I replied to, I don't think I have ever actually agreed with anything that someone calling themselves a libertarian has said, that I remember anyway.
