I don't know much about her outside of memes...
SHe was an also ran youth swimmer for Bongland, then she started complaining about trannies in her locker room. I have a little experience of Poser, as I was banned from her chat, for "constructive critiquing", she's thick as pig shit, and I think she's just grifting off of middleclass bints. She sells stickers and mugs, crap like that.
There was a stream she did... she tried reading a childs version of the David vs Goliath (two OT terfs), she was terrible, she has no rhetoric other than "I don't like it". The thing about terfs... they are just as dis cog as trannies, they have no logical argument or system, just shrill emotive language, then cringe flirting, when that fails, then all out sectionable rage.
She's like Commie Farms, if they were sincere in their beliefs, they'd shut the fuck up, as they don't really help the "movement".
Is Posie Parker suspicious?
Poser is the kind to let her followers get gay op'd. There was a comic called Mark Thomas, very left wing, did a thing about walking around Gaza (note: not through it and he ended up monetizing the events of a Police Intel officer infiltrating his fan base/protesters/useful idiots, by writing a book about the said pig earwigging and grassing them all up.
Mark (being the leftie navel gazer) opens the book saying how strange it was that this bloke stayed behind in the station, after certain members of the protest group got put in the cells. It's like Dude, what did you expect?
Poser (and joshy) both have that, they are too egotistical to see that they are the people who let in the narks and sneaks. She tried some Political Party nonsense and lost her deposit, so... maybe she isn't going to be much of an asset (regardless if she knows it or not).
Doesn't really fit well with the "working clawse" background she touts.
She's one of those fembims that have a husband behind the scenes, prolly using her as a tax write off. "Working class" doesn't really mean anything, none of these people will admit to being middle class. As she was competing youth swimmer,I doubt she was, that's middleclass parents taxing you around.
