This would be great. Unfortunately, people especially in large groups don't seem to have the emotional strength to withhold from doing that.
These mass conversations quickly devolve from debates to name-calling and the click-incentivized media is quick to encourage it (more outrage = more clicks = more ads = more $)
Given that this is the first time in several decades that white racism and "neo-nazi" beliefs have broken through into a national news story, I'm going to say that you're flat wrong on this.
Being called e.g. a feminazi by right wing nutjobs happens every day. I don't believe CloudFlare has ever canceled the registration of a feminist site because of it.
This situation was different. It was more serious. The crimes were more obvious, and more hateful. And it's simply not about the name-calling that you think you see against whoever your favorite group (gonna guess "not feminists") on the internet is.
And when serious evil shit happens, I want to live in a world where I can trust moral people to agree that it's serious and evil, and not equivocate to make a bunch of glibertarians feel better.
I'm not saying Charlottesville wasn't bad. I'm saying that the practice of calling everyone who doesn't agree with you a "nazi" dilutes the meaning with bad stuff actually happens (like Charlottesville). As bad as that was, there's only 4,000 KKK members in the US. That's a lot of people, but that's a crazy small percentage of people in general overall. At a certain population number, you'll have a set # of people that have hold terrible beliefs. That doesn't mean it's okay, but it might just be reality. Given that, I still think the best way to engage with those people is to engage with them - not to name call. Case in point[1].
You don't need to infer who my "favorite groups" are. I'm more interested in actual discussion than playing team games. Some of my favorite people in the world to talk with have complete opposite viewpoints from me. We may not agree, but being able to hold a civilized discussion helps each of us learn. That would never happen if we didn't talk and just called each other names.
Sorry, the notion of farcically inappropriate analogy to Nazi Germany is so common and pervasive that we literally have a meme for it.
It honestly seems like you're saying that companies like CloudFlare can't take a stand against real-life, actual nazis because Godwin's Law happened.
And that's why folks like me are so utterly horrified by the behavior of our seemingly moral counterparts on the right. We watched political discourse go off a cliff in the past few days and you guys all want to just wave it off as no big deal and have an argument about statues and domain hosting and stuff. It's a big deal. Not something to Godwin about.
