If you really don't get value out of a platform then it's definitely a good thing to withdraw, but personally... I find there are plenty of interesting things I can talk/post about without flipping any major rage behavior. And I have lefty, liberal, and conservative friends, religious and anti-religious friends, friends who are interested in high/intellectual culture and friends who are not.
I do sometimes offend people. Anything that prompts people to evaluate themselves or their models of the world or their particular value-set runs that risk. Sometimes I have things to say that are likely to do that. Like, for example, the suggestion that maybe a personal capacity for diplomacy has as much to do with the ability to hold wide-ranging conversations as much as the foibles of platforms or people do.
Some topics are especially difficult, but there sure seem to be approaches that minimize the heat-to-light ratio in discussions.
