this is a real-life exchange that took place between a lesbian activist, and a trans activist. the lesbian asked the trans "What's the cotton ceiling?" and the following exchange ensued (if this is confusing in any way, its either my fault in formatting it, or its the fault of the trans for making such little sense in the first place. the lesbian was totally clear at all times):
Not only is their a Cotton Ceiling, their is also a genetic DNA Ceiling that Transgender people will never, ever break. It's a barrier that they will never, ever be able to pass.
