I don't know about that ... my parents are libs and so is my ex. I love all of them to death. I wouldn't call them "evil" or "stupid" ... just intellectually dishonest and lazy ... and maybe even pathetically naive.
You're kinder than I am. I went to visit my Uncle in New Mexico, an Air Force vet who served during Vietnam (and, sadly, an ultraleftist). I had to listen to him drop f-bombs all over the place regarding Reagan, Dubya, Rumsfeld and the like. After he was done with his schtick and pontificating on how we've messed up the Middle East, I asked him point blank... "So, what's your solution ?" His answer, "I dunno." I think the "stupid" fits.
