Actually, human biological nature is an observable rejection of homosexuality.
Humans are not designed for homosexuality, and in fact, many of the practices are detrimental to our biological well-being.
So no, the biology is not irrelevant at all. In fact it is indicative of our overall design and purpose. Therefore it is very relevant, on it’s own.
I agree, biology supports our claims, and taken to its logical conclusion, homosexuality is simply a dead end. If we had two divergent human societies that did not rely on science’s intervention, where one was men reproducing with only women, and the other was men having intercourse solely with other men, one would carry on, and one would die once the youngest male ceased to exist. I don’t care how learned someone thinks they are, to go beyond this is silly. This isn’t 1996, and we aren’t living in the movie “Junior.” Generally people who want to defend human reproduction using only men breeding with me, want to introduce sciencetific help to enable some “miracle.” How convenient. Labs and this sort of science do not exists for lions, and did not exist a century ago. Go put a thousand men on an island or put 100 women (who aren’t already pregnant by a
man) on one, and come back and tell me how many are left 200 years later.
But to go down that path begins to miss the point. People will look for “facts” to support their endorsement of the harmlessness of pornography, gay adoption, contraception, and a host of other issues.
Depending on the source, we can argue facts all day. Stats can be skewed, and debated.
God cannot, and if you listen 100% to His word, there is never a slippery slope. Alpha, Omega, Beginning, End. Something is, or isn’t.
I simply don’t have the time or energy with a family and full time job to argue with people who refuse to listen to what God has already said through the Church.
If they are going to ignore God, what makes you think they’ll listen to us? People who show hurbis towards the Lord generally have no issue showing even more towards humans.
