I agree with you. However, something caught my eye. You mentioned that you were horrified and then mentioned that they call us "repugs" over at DU. Is that really any different than "Rats" and other names for them, here?
I have no problem with the denizens of DU calling us repugs since it's obviously a play on the word repugnant.
Being called fascist, repukes, pukes and other like names go over the line because it makes their view of us as something less than human. If you care to find out what other names they like to bestow on us, I'd suggest you go take a look for yourself.
