According to a recent survey, 0.3% of the US population--3 out of 1000--identifies as transgender: http://www2.law.ucla.edu/williamsinstitute/pdf/How-many-people-are-LGBT-Final.pdf And based on Lynn Conway's analysis, 1 out of 500 people are transsexual--suggesting that 3 out of 1000 trans people may be still too low:
But despite all this, I keep seeing numbers, commonly cited by cis "experts", that transgender people represent only 1 out of 10,000 of the population, or thereabouts.
Really, what are you afraid of? That maybe, if you're so wrong about this number, you're wrong about everything else you presume you know about trans folk?
Well, that's OK.
Because, you know what?
And you should get over it now--and then start listening to trans folk and taking what we have to say seriously for a change.
