Gryffindor
Gender Identity is real, and takes precedence over reality. Unbelievers will be punished.
You are: Stonewall; The Witchfinder General.
Hufflepuff
Gender Identity is real, and takes precedence over reality, but the existence of unbelievers is grudgingly acknowledged. Unbelievers will be tutted at, and shunned.
You are: A Liberal Feminist; The Church of England circa 1950.
Ravenclaw
Gender Identity is not real, and reality should take precedence, but the existence of believers is acknowledged and wearily accepted. May attempt to deprogram Hufflepuffs, with variable results.
You are: a TERF; a suspected witch.
Slytherin
Gender Identity is not real, and biology is destiny. Attempts to escape current local cultural norms for your sex (up to and including 'transitioning') may actually be a capital offence.
You are: one of the few UN states that currently ban transitioning; The Taliban.
To those who take issue with the allocation of TRAs to Gryffindor - come now! We all know that Gryffindors are self-righteous idiots with main character syndrome.
