It's not open to debate because the site does not allow the promotion of homosexuality. From a Christian standpoint it is a pretty one sided argument since nothing in the Bible would support it.
I did a formal debate with Freodin who sided with male homosexuality and who defended it., so apparently the Forum does allow such lifestyles to be promoted or defended as morally acceptable. I would be willing to debate this matter with you but like yourself (Christian) , there would be no defense of the life style. It would be a swapping of factual information rather than a pro/con debate. Personally, I prefer supporting a dissending view against a pro-homosexualist but id be willing to kick around ideas with you .
