Okay, back to what you said. 30% being attracted to the same sex in any way, including bisexuality, is a large shift. People tend to have a mistaken perception of these things due to media misrepresentation. The percent of all people attracted to the same sex, in any way, is around 7% for men, and 15% for women [1], across a study of numerous Western cultures from 2016. And those numbers themselves are significantly higher than the past as well where the numbers tended to be in the ~4% range, though it's probably fair to say that cultural pressures were driving those older numbers to artificially low levels in the same way that I'm arguing that cultural pressures are now driving them to artificially high levels.
Your second source discusses the reason for the bans. It's overwhelmingly due to sexually explicit content, often in the form of a picture book, targeted at children. As for "sexual deviance", I'm certainly not going General Ripper on you, Mandrake. It is the most precise term [2] for what we are discussing as I'm suggesting that the main goal driving this change is simply to be significantly 'not normal.' That is essentially deviance by definition.
