My issue with them is being intolerant towards anyone with a different viewpoint. I know pretty much every group, political or otherwise is tolerant towards other opinions but they take it to another level.
One day all the free speech they are tryng to block will blow up in their faces because of some of the very ideologies and groups they try to protect would do much worse to them for speaking out if they are eveer in a position of power, IE Islamics, Communists, BLM, etc. Or they will end up fighting among each other eventually, or they will piss off the wrong people in the wrong town/city and find out wearing masks/coverings, carrying any kind of weapon and destroying property was not such a good idea that day.
Personally though the biggest thing is they cant seem to mind their fucking business.
