Nauticant thanks for that link! Fascinating that Wikipedia is showing the old definition/entry & the new one - written just days ago, on 4 Jan 2019 - side by side. It's such a good example of the way TRAs are constantly manipulating language, changing definitions, & shifting goal-posts to sow confusion & get everyone else to fear saying the wrong thing.
I found it hilarious that TRA transwomen actually went to Wikipedia & insisted they change the "cotton ceiling" page to make it clear that it refers to transwomen's underwear, not the underwear of the lesbians transwomen are always trying to bully into having sex with them. These guys always have to be centered, don't they? It's always all about them. (Them & their fucking fetishes for wearing ladies undergarments coz that's what makes their dicks hard. Sheesh.)
However, I was disturbed by the deeper implications of the new definition. Used to be, the cotton ceiling was seen as a barrier protecting lesbians from the sexual incursions of transwomen, & that definition of the term implicitly portrayed the transwomen as interlopers & aggressors. But the new definition makes the cotton ceiling seem like it's another oppressive barrier that transphobic "cis" people, in this case specifically lesbians, have cruelly imposed on transwomen to deprive them of their rights & make their lives miserable.
Soon enough we'll probably be told that "not cottoning to" the sexual demands transwomen make of lesbians is "literal violence" just like misgendering. Fortunately, we women have "cottoned on" to what these guys are doing.
