Sean Penn on Prop 8

I'm watching Keith Olbermann right now, and he's showing Sean Penn saying that supporters of Prop 8 should "reflect" on the hatred they are causing. Excuse me?!!! What about the hatred that opponents of Prop 8 have demonstrated? Oh, but that doesn't count, I guess. It's the same "logic" that says liberals are "tolerant" and "open-minded." Mr. Penn, with all due respect, you do your own reflection, and I'll do mine.
