Hey David, I posted that video. Glad to help.
First- I think that yes, Era posters were a bit too reactionary about his views on Milo, etc. The fact is, I held those views too back in the GAF days. I wasnt too popular about it either. The fact is, i DRASTICALLY changed my stance on it when Charlottesville happened. It was the moment that I realized it wasnt just talk anymore. That "marketplace of ideas" you preached about is great -on paper, but that same 'marketplace' also produced a product. A product of hatred, white supremacy, etc. You also stated "the better ideas win in this marketplace". Ok- just like you ask- "who decides what hate speech is?", I'll ask: who decides what "the better ideas" are? Nazis? Authoritarians? Because thats what the 'marketplace' gave us in 2016. A far-fight slide into looneyville where Nazis and Nationalist are coming out like they own the goddamn place.
Im pretty sure most of us agreed in tbat 'marketplace' in the first half of the 1900's thats Nazis are bad. Agressively. I travelled down the Youtube rabbit hole of these fuckwits a while back. All of them. The fact about them is simple. They're grifters plain and simple. They arent bringing a product to that marketplace. They wanna BE the marketplace. And theyve been exposed as thise things already.
The truth is, I agree with you. Fuck it, let em have their platform. Let them get their ideas out there. But with a caveat. Lets all agree that omce weve discovered their "ideas" are cancer, we do with them exactly what we do with said cancer. We fight it aggresively until it goes away, or it destroys us.
If that 'marketplace' always produced "the better ideas" Martin Luther King wouldnt have been deplatformed if you know what I mean. The civil rights era would have concluded with actual civil rights. The wouldnt be slipping into a fascist hellscape, government would function properly and climate change wouldnt even be a conversation. There would be a far lower number of poor and homeless, and we'd be a much happier society. But none of that is true. Because that "MARKETPLACE OF IDEAS" is flawed. Why? Because its filled wall to wall with shoddy salesman, and the marginalized people in that marketplace are goddamn sick of hearing ---IDEAS---.
But yes, I agree that folks throw around the term 'alt right' like its candy at the local parade. Its frustrating because 1)it diminishes the weight of the word, and 2)Its a word for Nazis. They created the word to try and make their shitty "ideas" to go mainstream. People using that work are playing into that scheme.
But overall, being about free speech is just fine. But society also has the freedom to show you the fucking door if you ideas are shit.
