Someone said: On your above point- why should you be married, to someone of age of the opposite sex, before having sex?
I doubt if anyone is very often, even of the Christian persuasion. According to statistics, in the 1950s one in three brides was pregnant. That accounts for a third of the married population at least. There were no doubt plenty of girls over twenty who were pregnant too. So those couples had sexual intercourse before marriage and no doubt many were Christian. Today those of non-Christian religions are more likely to eschew sex before marriage.
Someone else said the word ''Gay'' was perjorative; I did not know that. I first heard it used in 1965, when I was fifteen, and was told that it was a word homosexuals used to describe themselves but nothing about it being an offensive term.
