Seriously, just stay here and occassionaly go to OT for the funny threads. I guess TV/Movie threads are relatively save to. Stay away from Gaming, stay away from other communities, stay away from political threads, LBGT threads, gender threads and religious threads.
It's good here, safe, enjoyable.
I still go to gaming a fair bit, but you just got to pick your threads wisely. The Steam thread is usually full of good people for one example.
