The Left loves Giuliani? Go to DU or some other Leftist forum and tell them that. They will think that's ridiculous. All Mayors and other public officials in NYC march in parades. That does not mean they agree with the organizers of it. There are public officials who march in the St. Patrick's Day parade in spite of the fact that they disagree with the policy that forbids Irish gay groups from marching. It's just standard politics.
