How will our permissiveness affect the health and well being of our children and grandchildren?
Let me give you a metaphor in
"Fermat's last theorem" . The theorem has been proved to be correct, but the proof of it is massive, requiring many many pages of equations to demonstrate.
So too is the proof required to demonstrate how Homosexuality and general moral depravity will eventually affect the health and well being of your children and grandchildren.
It's easier to just look at how such things have worked out in the past. For example, many people are familiar with the "Victorian Era", which was a period of great prudishness and imposed sexual restraint. (Incidentally, coinciding with England's greatest rise to power. )
What many people do not know is that it was preceded by the "Georgian Era", which was a period known for it's sexual debauchery and excess.
The Georgian Era saw huge swaths of the population dying from sexually transmitted diseases, and the mortality rate was becoming a threat to the nation's ability to defend itself.
I used to have better links to these details, but that was several years ago.
The point is, the Victorian Era was a necessary consequence of the previous generation's excesses.
