How about people that donate to fight the existence of polyamorous marriage licenses? Do you want to get them fired?
> there are no good rational reasons to do that
If you lived in the south bay area like I do, you'd suffer far more oppression from people with houses that oppose any and all kinds of development, than you would from the government not recognizing gay marriage (if you were gay). These people cost me thousands of dollars per year, and they make poorer people even worse off, driving them out of high-rent communities into far more dangerous areas and making them spend time and energy commuting. If some home-owner from west of El Camino that donated to the "Residents First" candidate's campaign in the Mountain View city elections became the CEO of Mozilla, how should I feel then? His cause is based in purely wicked selfishness, not some arbitrary nonsensical moral axioms or reasoning that you might call irrational.
At least Eich donated against Prop. 8 because he thought it was the right thing to do. He didn't gain any personal benefit from that donation -- it was at quite direct harm to himself (to the tune of $1000). That donation is actually a positive sign of moral character, relative to most people's bland non-contributing apathy. He just has bad moral axioms or couldn't think about this matter rationally.

I don't think you have an accurate model of how the average pious Christian that lives in California would behave (assuming that's the root cause of Eich's choices). You've come to false conclusions about what donating to anti-gay-marriage causes implies about one's personal attitude towards gay people. I'm sure there's some form of hypothetical marriage license that you wouldn't be in favor of, but that doesn't mean you're bigoted against those people. The state doesn't approve of anything but nuclear family marriage and its same-sex facsimile. I don't think that you'd be evil or couldn't be reasoned with if you believed that the state should encourage this social structure, it's just that your moral axioms or your views on what marriage is for are (probably) different than mine.
Actually, I'm just trying to be persuasive. The real reason you're wrong is that your opinion is built on your delusion that you and other people have free will, specifically, that of Eich having it. Going from the free will to no-free-will perspective, your attitude towards Eich maps to an attitude towards the universe being imperfect. So it happens to be imperfect in a way visible at the top of Mozilla. Big whoop.
