Not so much a debate about homosexuality, but it went like this. I walked in on this conversation, and it started with straight guy saying that he was secure enough with his sexuality to make out with another guy to make a homophobic person feel uncomfortable. My gay friend got offended by this, because he sounded like a closeted guy. The conversation continues, physical threats are issued, other person doubts said threats would be possible, gay friend thinks it's because he was gay. Conversation eventually gets defused, people calm down and we leave his house.
