But the procreation argument doesn't make sense, unless gay people are biologically incapable of producing children.
And let's face facts - closeted gay people have been producing kids for millennia.
So - homosexuality in itself cannot possibly be dangerous to society.
What would be accurate is this:
"Homosexuality is dangerous to society, when everyone becomes gay and penises and vaginas cease to function properly".
In that hypothetical situation, there is a danger to society. However, as homosexuality is not common enough to pose any threat to human existence, I think that it's safe to say that it's not a danger.
Think of it this way - a teaspoon of Ribena dropped into the River Avon is not going to make everything taste of blackcurrant, right?
Therefore it's not accurate to say that Ribena is a danger to the taste of water in the Somerset region.
