most demographic checks put transgender people at 1% of the population.

uk population is 68.5 million, that makes roughly 685,000 transgender people.

the upper bound of 'hundreds' is 999, 999/685,000 is 0.14%, a regret rate of 0.14% at the highest is incredibly low...

Is trans people a fad? 0.14% detransition, that's literally hundreds!
