I think /r/ChangeMyView has a really good approach to this sort of thing (I'm using them as an example a lot here, but it's because I think they really do run one of the highest-quality communities on the internet). One of their core rules is that people posting there have to demonstrate that they're open to having their opinion changed - they can't use the post just to soapbox. There's a lot written about it here, it's been very well thought-out: https://www.reddit.com/r/changemyview/wiki/rules#wiki_rule_b https://www.reddit.com/r/changemyview/wiki/rules#wiki_rule_b
