it's literally a straw man to imply people are focused on individuals in this situation, they are just worried about precedent and the future.
And we can even see what happens when platforms try to truly allow all speech. Voat [3 NSFW] is a good example, Gab is another example. The worst content takes over and your platform gets rejected by most of the world. Way before reddit banned the_donald they had to specifically delist it from the front page because awful content would end up being the first thing people saw. [4]
I also don't expect that Youtube or reddit or Twitter would end up banning all ideological content, religious videos will not get banned one day, discussing electoral politics will not get banned one day, we're not going to slide off the slope because the slope isn't there.

The thing that still continues to shock me is that there are people here that argue on behalf of white supremacists but still argue that they themselves are not, instead they are playing "devils advocate". At some point, let's call a duck a duck.
