I have a favor to ask for participants of this thread. I'm genuinely curious, and I don't care my about my karma points. What would be the primary reason for the proponents of the POV 'being sad about your grandchildren being gay b/c cessation of own genetic lineage isn't the best of approaches' being downvoted (like my every entry, and most others)? I believe it's an interesting conversation, and both side of it exchanged some interesting ideas debating in good faith, being reasonably calm and avoiding common fallacies, so I suspect some factors that are not obvious to me, like maybe the interlocutors are worrying that even discussing such topic might be a danger to their future rights of having offspring it all, or somesuch similar (just a guess, probably not even close to the real reason)? I'm trying to figure out what I'm being told, since downvotes don't come with comments/reasoning.
