Maybe the topic should be being Toxic in Game or in the forums regardless of who you are or what you are really isn't Cool whatsoever if you're guilty of such.
Everybody from A~Z maybe could try to be nicer to each other plain and simple. Just try and talk to other folks like you yourself prefer to be talked too most folks prefer nice people than buttholes.
Old Saying, Respect begets Respect. Nobody has any reasons to disrespect anyone on a forum or in a game. You don't really know folks personally so why act like a jerk towards someone you don't even know! It's pointless and does nothing!
Don't troll, Don't Feed trolls, Try to be more understanding and not look for an argument or stir at every chance.
What some might think is joking someone else may not because you're not sitting directly in front of them and really hardly anyone knows the other personally. Some folks have crapped days at work and the last thing they need is someone spouting off at them when they're looking for a means of escape and have fun. Try putting ourselves in the other dudes shoes a few minutes because we simply don't know what's going on.
I guess that if we all tried to be more courteous and kind have a little patients and understanding things could be a lot better here and in game. A lot of the YouTube guys are bringing the Topic of Toxic Behavior out into the Public. I hope people will at least consider what those guys are saying....
