The double edged sword here is groupthink. If you are trying to have a discourse about being gay in a social network comprised of people from Saudi Arabia, they might flag your very loving and helpful posts as being hostile. Thus banning you from their network.

In the end, I think it would result in even tighter bubbles where all information we find uncomfortable is eventually filtered away.

I think a better angle would be to figure out how to create an environment that encourages open mindedness and willingness to let others be themselves without forcing anyone into our own views. Easier said than done, I know.
