Maybe i'm in the minority here, but inviting republicans from the bush years to speak at the DNC isn't actually that reassuring to me if I care about stopping genocide, or think that the US foreign policy as a whole is bad and wrong.

Hell I'd go so far as to say if you invite a ghoul like Mike Pence to speak at your convention, you obviously don't give a shit about LBG issues at all, and are only using them as a shied so that no one can criticize your absolute inaction over the past 50 years on all social issues.
