No, it doesn't make you a traitor.
But it does tend to put you in a frame of mind where you would punch needles into your eyeballs before you would take any position remotely close to one that Bush occupies. Right or wrong. This is why it's called "derangement syndrome."
At this point the Democratic Party would cheerfully see half the planet burn if Bush burned with it. I don't consider this a good thing.
It also causes one to question your knowledge of history, even within your own lifetime.
