Give me a break. Liberal democrats are some of the nastiest people on the planet. Neocons don't come off as vicious, at least to me, and I certainly don't like Neocons - Neocons come off to me as just a pseudo-conservative type of group. Any group of people that support wars all over the place and "policing" the world really turn me off but just look at some places like Dailykos and Moveon for some really nasty shit on the other hand.
And save that Tea Party bullshit too because they are a pretty small group on the right and still aren't as vicious as some of the other extreme leftist groups - these groups support extremist militant gay rights groups and abortion backers, black power communist groups, LaRaza brown supremacist groups and you name it.
