"I do think that it has become an abusive place"
Citings please. Every site has their fare share of frustrating experiences where people sometimes say things they may later regret (and in some of my (and others) cases, apologized publicly for it), as well as a small percentage who are just assholes. However, comparing PM to the likes of Twitter or other huge aimless social media sites is misleading and irresponsible. I find that PM is far more an accepting, welcoming and less harsh than other educational sites (SO for example).
Whenever the gods or janitors see blatant ad-hominem, abuse or even snide remarks that have nothing to do with the thread it's located in, it's swiftly considered and removed.
How much should I bet that if I review history, you've posted something similar to this numerous times in the past?
