It's insulting how you think incels are somehow confined to wearing their heart on their sleeve.

Last term I took a class on a topic loosely connected to gender studies taught by a feminist professor. We were 20 girls and 3 guys. In the context of that class I was a feminist. Think of it like method acting or whatever. By nature I'm a really bad liar - but at some point as a young teenager I noticed that I can fully believe something even though I know it to be false and that people don't seem to be able to tell I am lying once I've adopted my lie as a belief. From religious conservative to communist, from feminist to men's rights activist, from pacifist to advocate of terrorism there is hardly an ideological position that I haven't spoken about with the utmost conviction at one point or another (and all of it were/are lies). Of course I didn't just say "yes" to everything (that would be suspicious and weird), I took a position somewhat distinct from most of the attendants (most of my female costudents see feminism as a movement to create equal opportunity for women, I adopted a notion of feminism as a movement against the suffocating effects of toxic & prescriptive gender roles in general) and we seemed to get along great. There was no inkling of them sensing anything wrong with me, we often continued talking before/after class.
