I am surprised free speech has been lowered to the level where it is considered "enabling" to allow people with competing or even outright morally evil opinions and motivations to speak their mind. No less, one is some how unacceptable but a myriad of others, especially those far more powerful and more influential in this generation, are permitted. Are we legitimately worried about Nazis of all things in this time? Is there some giant oppositional force holding a metaphorical gun to the head of the United States, let alone the world? A fairly blatant double standard to focus on one group of detestable people but sweep the rest under the rug.
This is not comparing Nazis to Communists, Antifa to Fraternal Order of Alt Knights, Black Lives Matter to the Ku Klux Klan, and so on. They are all guilty of various crimes under their banners; everything from the Haymarket affair to the more recent Dallas shooting. If you are going to condemn the "Alt-Right Nazi Pro-White Nationalist" people who are exercising their freedom of speech, as they are permitted up until violence and action on their words, then you are expected to be held to the same standard with your "Socialist Black Lives Matter Antifa" member whose organization allowed a military style engagement to massacre policemen who were trying to maintain order. There is hardly, in fact, no difference in the two when their words become actions to injure or kill. Neither are maintaining civil order or the protection of others and both to their own extents are inciting violence; when it happens, both lose their rights.
You can mingle the details as you want - which is the reality, in that not everyone on either side is to blame - but ignoring the reality that they are two opposites of the same spectrum that often utilize violence is being willfully selective and woefully dishonest. I might have a greater issue with Communists in this time than I do Nazis, yet for no moment do I excuse the latter or support them. They are just as much my enemy and contrarian to my beliefs as the other, just significantly less prevalent in number and influence. One is just glorified by the ignorant and touted as some great ideal while the other stands as testament that their ideology is still evil.
