I think her intent was to say that this trans person was "creepy" back before they came out by sending DMs to women (lol, I don't even want to touch on that), so people should be wary, but knowing her lack of tact it probably didn't go over too well. Either way it's a massive overreaction to want to kill yourself over a misunderstanding.
I mean getting dogpiled by liberals over dumb idpol shit is annoying, but she doesn't understand why it's making her upset or try to rectify those feelings at all. It's always about how people are being big meanies to her because she's racist/transphobic/predatory, and she doesn't care to understand WHY people are being big meanies to her, she just deflects any blame by playing suicidal. Even most tumblr "woke" libs can now see that it's a very manipulative practice to claim being suicidal over a petty online argument and it really just makes you look immature and foolish, so I'm not exactly sure what she's hoping to accomplish here. I'd love to see screenshots of how that went down tbh, I feel like we're probably missing out on a lot of prime Steph sperging by not being in whatever fb groups she's in.
