Here's what I wrote for elsewhere in the thread: (so this was a 10 minute effort and by no means constitutes a final effort)

We do take homophobia very seriously. We want all of our members to feel welcome, and we want this space to be as safe and harmonious as is possible. In that respect, we do not allow homophobic remarks. Understanding that homophobia can mean a great many things to different people, we do have to establish its meaning. Homophobia does not simply mean the opposition to same-sex marriage - historically, Christianity has opposed same-sex unions and a number of Christians today still do. This does not itself suggest homophobia, though we encourage our users to take care in spelling out that opposition, understanding the sensitivity of the topic, and remembering that you are dealing with real humans. What we do believe constitutes homophobia is a bullying attitude that instills fear, comes from a place of hatred, demeans and targets individuals, uses inappropriate slurs, and is excessively flippant or careless. For further clarity, the following list showcases the kind of statements we believe to be homophobic:

insert thorough list here. I won't take this on at the moment, but we could establish this list later

Statements regarding capital punishment for sodomy are tricky. There are Christians who believe that the death penalty is the appropriate punishment for homosexuality. So long as a user follows our rules and takes care not to state this belief with obvious homophobia, we cannot remove that comment. These opinions do exist in real life, and we can't always censor opinions. That said, the downvote and hide buttons are the best strategy here; they are good tools to diminish the visibility and proliferation of these comments and are the best way to conscientiously object.
