I don't think anybody's contesting Eich's right to not get gay-married. And likewise, nobody's contesting his legal right to try to strip a civil right from gay people through California ballot propositions.
But I don't think one can to try to harm gay people and then expect to have no problem becoming the boss of a bunch of them. They have a right to express their opinions too.
I also think your live-and-let-live stance only works as long as others share the same view. Eich's donation is just the opposite of what you advocate: he refused to live and let live. Would you still be calling for tolerance if Eich were working against interracial marriage, or against letting black people vote, or working to have the Catholic church made illegal in America? I'm guessing not.
The normative nature that you touch on is particularly bizarre. All too often, "live and let live" is only something that must be respected when it's straight white men doing the living. (I'm a straight white male, and that bugs me.)
The "civil right" phrase is a red herring. You can define any arbitrary item as a civil right - let's say unborn children deserve not to be killed, and thus we should ban all abortion. Then we can talk about any CEO who's donated to Planned Parenthood as stripping civil rights from fetuses and should be unfit for CEO-ship. Gay marriage is at a similar level of contention. Many believe it to not be a a civil right at all until very recently, nor is it accepted by many cultures. Or some accept civil unions but not semantically marriage. If you think you're always going to be right, there will be a definition of "civil right" or just plain "correct" that is diametrically opposed to you.
