But without context, by this argument, we have to assume the "antifa" is also innocent as you can't prove motive, a necessary component of guilt.
what could the man in the wheelchair have done? nothing, that's what. all I see in the video is a bunch of bullies attacking a disabled unarmed man. and to address something else you said, damn right I will cry free speech. free speech is one of the most important things about America. putting people in prison just for saying heil hitler, or owning a nazi flag is wrong. yes, I said it. I will always oppose imprisoning people just for words. the reason germany does what it does is cause of their unique past and a fear of it happening again. but I will never believe that it can even be possible to happen in america. we have a different society and rules. the situation is different. and I will not throw away free speech just on some far fetched fear.
Advocating for genocide that Nazis have done before is a threat. All threats on lives must be taken seriously. Especially from groups with predecessors who have actually committed genocide. It's not free speech unless you think genocide is an acceptable view. ---
