Nonsense. My sister-in-law is a died in the wool leftist and my law school roommate goes to anti-war rallies. I would have no problems with letting either of them babysit my kids.
You're exhibiting the same type of small-minded thinking as leftists when you slander half this country's population.
BTW, I too have Leftist relatives - supporters of the party of Clinton, Condit, Kennedy, Rostenkowsi, McGreevy, etc. They too march in pro-Saddam rallies in SF. And, yes, I question their judgment.
