40. That is because in primitive societies and earlier ages, society feared underpopulation.

Many babies died very young. The challenge was to make sure that tribes and then nations had a high enough birth to death ratio to insure survival of their group.

Now, the opposite is true. Overpopulation is more of a threat, more to be feared, than underpopulation. We don't need to encourage childrearing as much as we did in the past.

In many cultures, homosexuals became shamans or priests. Thus, the association of celibacy with the priesthood in those cultures. That was, I believe, not true in the Jewish culture. Rabbis married and had families. In Timothy in the Bible, it is written that a bishop should be married and have a family. Nevertheless, the Catholic religion has the tradition which has become the rule that priests and bishops should not be married.

So, there is a very logical reason for the tolerance of homosexuality in our society today. It no longer poses a threat to our survival.
