To hurt 76 policemen is to go out of your way to harm others, and it probably was not just one person throwing dangerous things at them. Hence why i said, you are more likley to get killed in one of those rallys.So no fatality what so ever. Communism has nowhere a large platform, so people promoting communism or far left ideals is no concern of mine as they don't get into a position of power where they exclusively rule or determine the course of the government. Secondly these groups today are nothing compared to the past where they were funded by the Kremlin to destabilize governments in western, centrum and eastern Europe. Where they succeeded their rule is still fresh in the minds and where they failed the people are aware and they are very moderate in terms of what they promote, as they know what happened to those who promoted revolution on these streets in the west, they got murdered and hanged.
Luck or not, no fatalities took place, I ask this as they generally don't go out to harm others. Property damage plenty, most of those you also see rioting are generally anarchists an even smaller group that still believes it will get them somewhere, it doesn't look at Greece or even look at the protests and Brussels and how their entire message is lost due to these anarchist riots. Its counter productive.
So honestly this whole obsession people have with the "reds" is beyond me and is really not rational at all. I will gladly condemn them for property damage and anarchist behavior, but i won't call them murders, promoting the deaths of others. That i see as even someone on the right side a reaction to "alt right" calls of violence.
At the end of the day neither group will get far, also in this case i'm not even certain that it were these "left movements" people speak of as so far i have seen it was locals protesting a march of neo-nazism and all they stand for.
