(1) was a pro-tra libfem (not an activist, online or off, but I did believe most of it)
(2) dated an MTF
(3) realized that the current pro-trans discourse is pure bs and gaslighting (peak 1)
(4) posted about my experiences on (liberal) feminist subreddit, was downvoted and dismissed as a troll, because ''this never happens'' (peak 2)
(5) joined groups like r/itsafetish, started reading trans subs to find material for that sub (peak 3)
(6) found out about all the censorship in science, academia, journalism etc. etc. that the TRAs are pushing (peak 4)
(7) saw what impact admitting MTFs in lesbian spaces has on that space (peak 5, referring to r/AL obviously)

It's one of many reasons why I believe that internet is one of the main drivers of the spread of irrational ideas like these. If every day you see 10 people who constantly repeat x, y, z (transwomen are just like women, there is no difference, etc. etc.), but you never encounter this phenomenon in the real life (I did not know any trans people IRL), then you begin to believe those statements. And when you encounter the real thing, you begin explaining away all the incongruences, because you ''already know'' how it is ''supposed'' to be, and also you don't want to be a ''bigot'' by seeing the biological reality if your political ideology demands seeing something else. But I can only lie to myself for so long.
