Agree, Just what I said, violent ones. Of course that means both sides. As long people clearly understand that means literally all sides get charged and/or banned equally. KKK in Anaheim is very peaceful for example. They are a non issue but have a message many do not like. Can't ban people because you disagree with their opinion.

The anarchists, most hiding their faces, attacked the 6 Klansmen. They are NOT peaceful. They could and should be banned from congregating now and in the future.

Thank you for mentioning Germany-today's news in Germany.

  Like I said, both sides.
