I thought that number was closer to 1.5% - 2.0%
You are mostly correct. Those that typically engage in sodomite practices, both male and female, comprise about (maybe) 2% of the entire population.
Unfortunately, the hand-wringers that actively support their deviant practice would approach 10%.
Another 48% stand ambivalent as long as they aren’t the ones getting sodomized. Do the math.
