In the Old Testament both parties were to put to death and the method of choice was stoning. The act had declared those practising it as dead to the nation. So they were given a violent live burial. The same was true with adultery.

I mentioned this in defense of religion. From my perspective the bigotry is in the text because of the bigotry of it's human authors not because of the a divine bigotry or any institution of bigotry from the religions that maintain the text.

Though removing it from the text would be a step in the right direction if a religious organisation wants to distance itself from the acts violence in the text.

i think there is a mix of the standard disgust response when discovering a group of people indulging a form of sensual pleasure that seems alien, coupled with a scripture led tribalism spread by bigoted clerics (of many religions).

The germ of that clerical led bigotry is the oft misquoted Old Testament prohibitions most of the time. Even the Indian Right Wing take the principle from it's colonial history.

Secular bigots draw from a religious cultural history when they make their proclamations of 'tradition' and 'natural law'. Just as secular charities also pool from a long history of religious good works.
