The Bible has very explicit scriptures on the topic of homosexuality even labeling it an abomination. God’s word will not be altered or changed to make the practice of it as acceptable. Gay Pride will NEVER clear that hurdle yet the wilfull arrogance against His word will have a price to pay.
How about forgivable? The difference between the condemned in the Old Covenant, and the redeemed in the New Covenant, is the Blood of Jesus which is the only thing that makes us pure and worthy - despite our continuing sinful natures. Go through a whole day without a sinful thought/act and you can sit in judgement. Until then all you can do is resist your own temptations and try to follow the two great commandments.
