When i was young & in the police academy my law instructor had said to us that once we were on the street with that shield we had to have a thicker skin. People would be hurling all kinds of insults at us but thats not against the law, and more or less we'd have to take it.
People used to be able to discuss & disagree and then go on their ways, still friends. Today the skins are too thin, everyone finding offence at what sometimes seems everything. If u disagree, even if i feel i'm the enlightened one, if i have no counterpoint to make it's easier to just call someone else racist/sexist/homophobic etc.... I just rolled my eyes skyward when i read that article last week about a school teacher wanting to engage in whats tantamount to espionage by infiltrating tea party demonstrations and wanting to get as much camera time as possible by dressing as hitler, shouting Ni**er etc.
If these guys are whackos it'll come to light soon enough. Infighting like that benefits someone, theres reasons it's poked, prodded & enticed to continue. Someone stands to gain from all the division
