1. Volunteer. Somewhere, anywhere, for a good cause, for a selfish cause. Somebody will be happy to see you.
2. Stop trolling ourselves. As far as I can tell, all of the mass social media is trending sharply towards being a 100% troll mill. The things people say on social media do not reflect genuine beliefs of any significant percentage of the population, but if we continue to use social media this way, it will.
Disengage from all of the trolls, including and especially the ones on your "own side".
