Lack of geographically induced consequences (I'll get into those in a second), combined with the pussification of the American male, an sue for any slight culture and the vast majority of dumb people having access to smart phones has all combined in a pot to give birth to this overly aromatic crap stew which we have been eating and asking for seconds for a while now.
Geographically induced consequences used to keep people in check. Way back in the day, if you wanted to say something to or about someone, generally you were within arms reach of them. At that time, if the message they had to convey was offensive, idiotic, or just plain wrong, you were free to smack some sense back into them. The anonymity provided by the internet, when combined with it's far reaching capability allows people who would normally be to0 shy, stupid or idiotic to be paid attention to a pulpit from which they can spew their mindless drivel from relative safety. You can call me a punk all you want on facebook, but there aren't many people who would take me up on my offer to say it in person so that I could illustrate to them how much I disagree with their opinion.
Additionally, this "sue happy" culture lets people seek vindication (financially or otherwise) for any perceived slight. The problem is that what was once just "life" can now be so offensive that wagons are circled and lawyers are called. Not only does this strengthen the weak by giving them a false sense of power, but it causes those who would do the right thing to shy away from it due to the possibility of litigation. This feeling also creates a sense of entitlement because if one is to feel slighted, then they should be compensated for their hurt feelings.
Bottom line, I hate everybody (except for most of you guys, my family and girls with big boobs)
