Like being foaming-at-the-mouth socialist and Democratic does, right? Right?
Comparing a staunch conservative to a nut-job liberal isn't exactly fair. The liberal equivalent of a staunch conservative (McCain) is a socialist democrat (Bill Clinton). The conservative equivalent to a foaming-at-the-mouth liberal (Nancy Pelosi) would be the soulless, heartless and downright hateful republican (Ann Coulter).
As for as civil union/marriage thing goes, I'm all for the long overdue separation of the two. There are many who wish to get married, but not have to deal with the attached strings of common liability. On the other hand, some people don't believe in marriage but still wish to have a common security. If the two are kept separate, it allows more choice, and in turn, liberties.
