I strongly disagree with Prop 8, and therefore presumably his views on gay marriage, and I believe not supporting gay marriage does obviously make him a bigoted; but for what it's worth, I haven't seen any reason to believe he's ever "raged" about any of those topics, to anyone.

All I've seen is a donation to a bigoted cause (which is disappointing), and then a matter-of-fact public statement that Mozilla's mission is bigger than any one person and their political beliefs, and that he's only willing to discuss this issue in more private channels, which seems totally fair.
