You are overlooking the most obvious part of voting & that is demographics, the more chilled out communities don't care if you have a contrarian opinion, they will even upvote it if is well stated, there are communities who are interested in welcoming new people to join it rather than just isolating themselves to just the hard core elements.
Even a garbage place like /r/CringeAnarchy, which is a place that that have a bunch of lax mods who do the bare minimum to moderate, a place that should according to what you propose should be a hugbox for "alt-right" opinions, just cant do it. As circle jerky as it can get, it simple cant achieve the peak, new people keep on coming in, disagreeing with content, & getting upvotes. People posting cats instead of cringe, people are confused if they people are up voting stuff to cringe with or cringe at or just question if it is cringe at all & asking question of what the is going on. People keep on calling out satire posts instead of falling in line, people keep on switching to mock right wing cringe & /r/CringeAnarchy itself.
The places that do turn into hug boxes are not the ones that vote in circle cerks that can be hostile to contrary opinions & content, it is the subs who have mods that ban people with contrary opinions & content that turns into safe spaces.
