Despite the subtle ad hominem, yes, me too. Absolutely. I'm pro-gay marriage (or, more to the point, given that gay marriage is now legal in Portugal, the fight has moved on, and it'd be more relevant to say that I'm for gay co-adoption).
I think you're missing the bigger point here. There is one topic I definitely care about more than I do about gay marriage: The capacity to even discuss it, and the right to talk about and support that cause if I see fit. And this is very much a case of what's good for the goose is also good for the gander. If you're OK with blocking Eich's ascension to CEO due to his position, it's hard to justify how you'd then be against other people being blocked like this for holding unpopular opinions.
In my experience, stifling debate usually hurts minorities and makes it easier to maintain the status quo, so if you want to further a minority cause, you need to be able to have open discussion, so all in all I'd rather allow people to voice unpopular opinions — in some circles, I'll be the one doing it!
