They are using Nazi Salute and all these other goofy symbols to prove that they have their right to freedom of expression. They are intentionally trying to troll and trigger people to prove what they is the problem: intolerance on the left.
All one has to do is look at the San Jose rally, the countless innocent Trump supporters beat, Antifa assaulting and terrorizing countless people to see where they are coming from. No one protests these inflammatory BLM rallies, no one protests the countless rallies where they incite violence against people with opposing political ideologies. The heightened rehtoric on the left has compelled the right to up their anti to prove their point, to drive thru the messages they see as important.
We cannot single handheld condemn them and ignore the people that showed up to beat them up. We need WAY more dialogue in this country, less violence, less base ball bats and shouting over people and way more listening. These people, no matter how much I disagree with them, did not show up there to beat people up....the same, however cannot be said about the Antifa who showed up to "Bash the Fash",
And news flash to all the Antifa, the way to get more people to agree with these clowns is to show up to their rallies, put it in the spotlight and start beating the, down when they try to voice their opinions. Just ignore them. Antifa and BLM has pushed more moderate whites to support racist notions since probably anyone since Hitler.
