I've got a beard and beer gut, and look (as my wife tells me) like Joe Redneck. My family's been Democratic since around 1828, even through the civil rights imbroglio of the 1960s (doesn't hurt that my grandfathers were in unions, unusual in the South). I'm also a veteran, and tend to be pretty nasty to yellow elephants (of which my town is now full of, to my and many other veterans dismay). I always work the Friday night Democratic booth in the county fair every year, and I'm always getting people coming up to me, and wondering, "Why are you a Democrat?"
I always ask 'em, 'how much time do you have?' and begin telling them, starting with the 1890s and so forth. BTW, I have a magna cum laude degree in philosophy/religious studies and a masters degree in technology, so I'm definitely not typical in my appearance and attitudes. I am very negative towards right wingers and evangelicals (since I can beat 'em to death with their own contradictions, they tend to whisper in my presence - why, yes, I am a fairly large fellow with a VERY loud voice

).
The local chair of the Repuglican party here spent a short (got much shorter after this story got around) period being a substitute teacher in one of the middle schools. I got this directly from one of the students in the class: she informed the class, as part of their geography lesson, that Cuban women (yes, Cuba!) wore burkhas, since we all know that Cuban communists oppressed their women and took their cues from the Taliban. I've been going around ever since asking her (she's on the county election commission) repeatedly about the Cuban burkhas. She's tired of hearing it - and I ridicule her publically whenever I can.
Yes, it's childish, but the ReTHUGs are stuck in junior high school in mentality. I attack them pretty viciously. I'm actually relatively conservative for a Democrat, but I'd rather be a conservative Democrat than any sort of ReTHUGlican, or libertarian (a dope-smoking ReTHUGlican).
