I'm not GP, but your straw man is just as disappointing.
- Nobody here is saying trump supporters are fascists.
- Nobody here is even saying that the_donald subreddit represents all of Trump supporters.
So why are you playing that card?
GP is talking about the effectiveness of the deplatforming of hate speech in context to a subreddit that has been reported as inciting violence. The same subreddit that supported the Charlottesville Unite the Right rally that resulted in a Neo-Nazi murdering Heather Heyer.
Whether or not you think that extends to all Trump supporters, and are disappointed by that, is your own inference. Don't attack GP because of it though.
