No, that's a straw man. In his endeavors to deprive gay Americans of their right to marry we should absolutely oppose him, and publicly so. However, I don't think those endeavors should define the way we interact with him on all other issues. His position as CEO of Mozilla has nothing to do with gay rights, so—as long as that view doesn't inform his work—I don't think it's appropriate to hold it against him.

I'm Jewish, and I have friends and family who were affected by the Holocaust, so I do sympathize with your example. But I just can't bring myself to believe that a small subset of one's actions or beliefs define one as a person. I vehemently disagree with them, but I don't want anyone ostracized because of it.

And lastly, I realize this is a very emotional issue, but many people who oppose his resignation (including myself) do support LGBTQ rights. We have the same end goal, you and me—we just see different ways of getting there :)
