Civility

Why is it that civility is a lost cause among some it seems?

Among the many forums I participate in it is the most uncivil that are ever lashing out at others and in turn whining that they are being "abused" when they are called to the carpet for their incivility or are given back what they try to dish out often better - always better than they deserve.
Also, I have noticed that there are two characteristics these uncivil ones share in common ... 1) they are younger posters, 2) they are on the right end of the political spectrum.

It is a given that each generation feels a lack of civility in the next generation, but these posters go way beyond the pale, surpassing the 'standard' of incivility each generation perceives in the next.
It is no surprise as to the political bent either given the political campaigns of the right the past twenty years.

On one forum I participate I posed this very question, albeit, worded somewhat differently - it will be interesting to see who responds and what those responses will be.
