I think that both sides have done their fair share of crying wolf over the years. Neither party has clean hands on that topic. IMHO, the far left and right deserve equal blame in using inflammatory rhetoric to describe the opposition.
Personally, I'm tired of all the generalizations used to describe people in the other party. Not all R's are closet racists/homophobes etc and not all D's want God out of everything/pro-abortion etc. I think that some people are so focused on the R and D labels, that they forget that they are talking about people. Kinda like road ragers who get so riled up by a car, they may forget about the people inside.
I like to think that both parties (and 3rd parties) are mainly made up of centrists like myself, who certainly don't fit the labels the far left and right attach to one another. We may differ in our ideas of how things should be done, but we have the same goals for the country....peace, safety, prosperity for all. Unfortunately our voices are drowned out by the talking heads and extremists of both parties who are both equally guilty of tuning one another out.
