Pushback is absolutely crushed. It's impossible to really be an active user of most of these platforms without representing the desired view.

Can you think of examples of online platforms that combat this tendency?

One that comes to mind for me is Lobsters. I'm interested in other examples as well as mechanisms for striking a balance between civility and diversity of opinion.

Lobsters is invite only and I don't know anyone to give me an invite, but it seems like discussions there are pretty good from what I've seen.

The only other places I've seen that aren't this way are various chan style sites and oldschool internet forums, but those places have their own obvious problems.
