FYI -- Common sense & experience shows that the overwhelming anount of people in this society do not regard sex outside of marriage or sex for reasons other than procreation as "taboo".
...if that taboo is broken, then heterosexuals will start engaging in non-marital, non-monogamous sex, and cause all kinds of other problems such as adulterous relationships, children born out of wedlock and so on.
There are millions & millions of people in our society -- and on this very website -- who have had non-marital, non-monagamous sex with no consequences whatsoever. Same with sex for reasons other than procreation.
Great. Then people will vote to remove that taboo by electing people to state legislatures who vow to remove laws reflecting that taboo. Pretty easy this voting stuff.
