Repeat the first sentence from the wikipedia quote and ask yourself if it addresses everything you just said. Here’s a hint: it does.

I’m providing context for why numbers regarding transgender people are fuzzy at best and why telling someone they’re “fucking lying” about them is misguided at best.

Accurate statistics on the number of transgender people vary widely,[11] in part due to different definitions of what constitutes being transgender.[6] Some countries collect census data on transgender people, starting with Canada in 2021.[12][13][14][15] Generally, less than 1% of the worldwide population is transgender, with figures ranging from <0.1% to 0.6%.[16][17]
