I understand what you said about zeitgist and of course not one of us is immune to current thought and discussion but isn't that what progress is about; as time goes on, we learn more about ourselves and human nature in general. There was a time when people believed the earth was flat (some still do!), discovery is important so is the ability to admit we got it wrong and change our minds. It wasn't good to be intolerant, cruel even, towards people whose sexuality was different to ours. Certainly not good to give hormones, perform lobotomies and force fellow human beings to undergo horrible conversion therapy (which didn't work), nor to stick people in prison for just being themselves. I'm glad to be growing old in an imperfect but ever improving society.
In any case, what difference does it make to you, or me for that matter, what other people do if they are not harming anyone?

A bit later. I've been thinking about this thread and there's no doubt we do this subject to death on all Christian forums, I can never resist joining in - but am I (& others) making things worse by putting my oar in?
It might be better if we all ignored it when someone starts a thread on the topic, it's their problem if they have a 'thing' about the love lives of others. Perhaps we encourage them by responding. If we didn't their obsession could lessen and they might get a life.
