No I don't. What I wrote was that, in the end, opposition to gay marriage now, in this social context, is homophobic, and people who are newly minted now would be homophobic to hold that view, but we also have (or are) "legacy people" whose opinions were formed in a very different world in which gay marriage was literally "unthinkable." Opposition to gay marriage then did not constitute homophobia -- it was meaningless, like opposing unicorn marriage.
Let me give an example. Lincoln favored deporting the blacks back to Africa, or so I've been told -- that might be one of those myths, but let's assume arguendo that he did. In my opinion, that does not make Lincoln a racist. If somebody born in 1963 thought that... yeah, they'd be a racist. We can only be evaluated in terms of the time in which we were formed. Ideally, we keep an open mind and our opinions do change over time as we learn more and our surroundings change and we emerge from the parochialism of our upbringing, but like the very nice grandma who uses the N word, there are plenty of good people who hold obsolete opinions.
tl; dr: what I said was, I think it's possible for someone to hold a bigoted opinion without being a bigot.
