Syag, it’s a metzius that adultery is more prevalent than homosexuality. The only real difference between the two in contemporary times is that the former is widely acknowledged by virtually all as wrong whereas the latter was also so acknowledged until relatively very recently in history when through great political and media effort society was brainwashed into changing its views towards accepting its normalization. Something that has yet to occur with the former. (Give it some more time.)
Given that the former is far more prevalent, perhaps you can explain to us how that it is that you’re somehow able to “attest” that the latter is a “large group” when I think you’ll admit (correct me please if otherwise) that you don’t know of a “large group” of the former, despite that sin being far more prevalent than the latter.
You’re being unaware of any large group of adulterers isn’t because they don’t exist. It is because they don’t make themselves known to you. Which is far better than it they had made their sinful nature known to others. Yet the existence of the “regretful” homosexuals, you attest, are made known to you in a quantity consisting of being (even just from what you know and can attest to) a “large group”.
I acknowledge that you indicate that this “large group” of homosexuals that you attest to do admit that their sinful activities may not and should not be engaged in by themselves, despite their continually doing so, to their regret. But I do severely question how it came to be that they made their sin known to outsiders (such as yourself), whereas other sinners (such as adulterers, which as a much larger group would be better known had they made themselves known) tend to not do so; and appropriately not.
