Dr Drew has a theory that people’s mental maturity stops around the time they become sexually active. That definitely applies to Chelsea where she sucks and fucks the guys in her social circle to get what she wants. She’s likely done that since being an early teenager, which explains many things about her including her terrible fashion sense.
That was largely created by Adam Carolla musing about a humans ultimate biological imperative: reproduction. If someone starts having sex at a way too early at an age, when their parents is responsible for every other need in their lives, then something in the brain will see it as mission accomplished, it's time to kick back, relax and wait for the babies to roll in. In that particular context he was talking about the lives of 12-13 year old boys and lecherous female teachers but it also applied to more physically developed 12 year old girls and the skeevy dudes that starts sniffing around.
He followed that up with saying that people like Bill Gates and other nerds(this was in 2002 maybe) never got laid in high school and that's why they're rich instead of living in a trailer park or doing manual labor. They had to put in the work to have sex at some point in their lives.
On Sarkeesian and money and this was a couple of years ago so I might not remember it right, Petite and the negress might still be employed but even when FF had money and I looked at the financials it certainly seemed like at least Petit was only paid 12k a year or something like that. It's don't quit your day job kind of money. Anita had a higher salary but not what you would expect, 20-25k IIRC, so I suspect that she was pocketing money from speeches and I've seen other people in the non-profit business make money like that. Over the 2 or 3 financial years that I looked at their largest expenditure was always fundraising, even when all their outreach/effort/grants were summed and compared against it.
CON and Chelsea was one such org that FF gave money to so they were intertwined. Zoe and Anita probably doesn't mix well otherwise, Anita at least have the tenets of established and stodgy 80's/90's feminism while Zoe is more "everything I like must be good because I'm a good person" and if she doesn't like anything/someone (tumblr mentality) then it must be sexist/bad/evil/harrasment.
Sarkeesian is at least respectable in that she has an ethos or ideological axioms even if it's dumb.
The difference that separates Anita and Quinn, just to put them into separate buckets, is that one sees herself as doing a great work, the other sees herself as great. I suspect that at the UN thing both of them thought that the other one was riding their coat tails, for different reasons(FF renown vs actually being Zoe Quinn).
