For me, the main uses of FB is free communication with friends and family, and populating my news feed with interesting, funny shit. Anything attention-seeking, bigoted or annoying is met with an unfollowing (so that I'm still friends with them, I just don't get their shit clogging up my news feed).
If you have any serious concerns, are being harassed, or just need someone to talk to, feel free to contact me via PM
