I don't agree with banning controversial views in general, because anything can be judged as controversial depending on who is doing the censoring. Plenty of progressives have been deplatformed from colleges and different other places for example due to their views on certain topics, many of which have been 'judged' as bigoted in certain cases.
In my view, the moral obligation goes as far as calling out hatred on the merits.
But as i said earlier in this thread, i'm not gonna lose any sleep over not seeing a bigot's content on my dash. Of course, pragerU still has an entire youtube channel dedicated to pushing out bigoted content, so no real luck avoiding it it seems
the issue is that you're creating a slippery slope by conflating bigotry with a difference of opinion, positing the issue on the perspective of others rather than with the views themselves. sure, people can label progressives as bigoted, but actual bigoted views - mysogyny, homophobia, racism etc. - should not be tolerated in any space, regardless of political affiliation. bigotry is bigotry, and should not be likened to a difference of opinion or just another political view - not giving it a platform is not the same as denying someone for their political views unless you falsely liken it as such. they are not views that can or should be debated on the basis that they have some worth - bigotry by it's very nature is illogical. you can't meet in the middle or compromise with bigotry as doing so still gives into it.
to that end, deplatforming has been proven to work against people spreading bigoted views. milo yiannopoulos has completely dropped off the face of the earth in terms of relevancy when his twitter was banned and his book deal was shot down, whilst alex jones only seems to exist as an immortalised fictional character in memes mocking him after he's had his own social media presence banned. their own hateful rhetoric has barely resurfaced after the fact; people have largely forgotten about them. it didn't matter that people were able to criticise them when they still had their platforms, they were still able to spread their bigoted views just fine. if you're a minority who's the target of these people's bigotry, no matter how much they're criticised, they're still enacting violent rhetoric against yourself to anyone who listens, allowing it to fester and spread. if a platform actually gave a shit about mysogyny, racism, homophobia etc., they shouldn't let that happen.
