Unfortunately, I have to be the first to ask you where you heard about all of these "wackos, extremist, & religious fanatics?" From the media? Sounds like it to me.
Just because the media says they exist, do you believe them? Hey, its thundering outside right now...
THE SKY IS FALLING, THE SKY IS FALLING!!!!!
Get my point?
But yes, there are people ON BOTH POLITICAL FRONTS whom are far enough to their respective ends that it is surprising that no politicians like Feinswein, Shmucker, Hitlery and Klinton weren't off'd. I guess it comes down to why we have gone downhill as a country....
PEOPLE DON"T WANT TO MISS THE LAST EPISODE OF FRIENDS!
People are happy with their lives, why upheave everything over *GASP* P O L I T I C S???? They're happier sucking down fat free Haagen Das coffee ice cream while watching the socially degenerate "Will and Grace", than going down and killing a politician over his political views. Not to mention, most people have a healthy fear of hell, karma and jou jou.
People are people, why ask why?
