Gallup doesn't make any bones about it, the bulk of the uptick was in Gen Z women identifying as bisexual. They also didn't hesitate to observe that the bulk of bisexual-identifying people eventually settle into a heterosexual relationship.
So in point of fact we haven't had a 10x increase in homosexuality, we have had a surge in young women who are statistically likely to settle into hetero relationships declaring themselves as bi.
In my opinion it helps nobody to muddle or politicize the statistics. For me it's hard to not draw the conclusion that heterosexual young people want to be allies and are declaring themselves as bisexual and perhaps experimenting a bit as a show of support. Seems more likely than the idea that a full fifth of the human population that has been sexually oppressed since the dawn of history, but it's open to interpretation I suppose.
