It seems there are always thugs around who use politics, sport or whatever as an excuse to beat people up.

Typical liberal jargon trying to pacify a violent thug group as mere troublemakers looking for a reason to cause trouble. Fact is though that troublemakers don't don in a specific dress style by the hundreds, sound para-militarized by shouting out fall back commands during protest, sending out tweets that say they realized some may not be able to engage but to show up to support the cause (meaning if you can physical fight then fight), pre-planning to add quick dry cement to milkshakes to throw at people are all signs of a domestic terrorist group out to terrorize people over differing view. Watch some of of the video clips from this past protest and in it you will see there are no other people in the crowds involved in the scuffles, violence hiding their identities and that's because they went there to hold a rally in support of each other to express themselves in a peaceful manner, there was no reason to hide who they were as they weren't coming to be engaged in fighting.

It's easy to want to lay blame on a US president who mocks the press. There's a huge difference between mocking the press over inaccurate, slanderous, bias interpretations of stories and actually jailing, beating, and killing reporters. Maybe before you lay the blame at the presidents feet why don't we look at the number of Hollywood liberals over the years who have assaulted the press, you may want to start with Alex Baldwin as he is famous for it.
