Is ‘going postal’ the issue raised by the OP, or is it societal anger in the main?
There is no question that American society prior to the late sixties was much more polite, considerate, and well-behaved…and less crass, classless and vulgar…than it is now.
It the permissiveness that grew out of the counter-culture movement of the late sixties, combined with the instantaneous anger and condemnation visited upon anyone who dares question any aspect of anything the left proposes with regard to its pet causes, that is responsible for the anger permeating society today (or to the extent that it does exist, that is).
Any number of people will be along shortly to allege: a. society changed all on its own with no leftie influence; or b. society had to be changed to eliminate racism.
Both are laughably incorrect.
Then you have the practice of the left wherein anyone not hewing unquestioningly to anything and everything proposed to correct societal inequities is subjected to anger, insults and even legislation to ‘bring them in line’. Look at the way people are reviled on this board for being prosperous, for driving SUVs, for disbelieving global warming. Nothing is up for debate or discussion when it comes to the left, it’s all my way or the highway - and fuck you if your way isn’t my way.
Now, with the advent of Limbaugh and Fox the right finally has a way to rally together and fight back, and, given both the breakdown of societal mores since the late sixties which has affected people in both ideologies, and the fact that it takes two to tango, the right and left are now at each others’ throats.
People simply cannot be allowed to behave any way they want (no man is an island and all that) in a civilized society, and yet the desire for virtually unlimited personal freedom is one of the key hallmarks of liberalism…and it is out of this belief in ‘personal freedom’ that so many people feel free to act like crass, vulgar, angry assholes today.
Or so it seems to me.
