I think she was just a rotating guest who was in place of Luke or FreedomToons. Not sure if she's still on Pop Culture Crisis because no one watches that show, but I wouldn't be surprised if Tim exiles her at some point for using gamer words.
The funny thing is Tim's stance on race differences and achievement differences are purely political to show people he's no racist. When there's real study and science that is done on intelligence it actually shows the quality of the school doesn't change things that much and at most accounts for 10% difference, so just improving schools and resources doesn't actually change things substantially.
Good clip of a scientist discussing some of this on a podcast and I'd suggest people watch the whole episode as they get into how you're basically not allowed to look into if genetics plays a role in intelligence because the last few times they did it things didn't look good for minorities when accounting for things like opportunity and schools.
They even talk about a whole study that was done where the government set up Potemkin Schools to give under privileged children the chance they needed to prove it was just poverty, and turns out the only one of these schools that showed success known as "The Miracle In Milwaukee" was faking all of its data and every other school in the program showed you get about 5-10% in difference but the kids still don't come close to achieving things "privileged" students achieve. Then the whole thing was scrapped and forbidden because one researcher said maybe they need to start considering genetics as part of the equation as compensating for school funding, food, teachers, etc wasn't working.
It's also why hacks like Malcolm Gladwell are so promoted probably, because they find a way to spin it to show that the reason unprivileged people of one race still succeed (Asians and Jews) isn't because of something innate to them or their culture, but because their underprivileged situation is actually secret privilege because it makes them tougher and more resourceful, but those kids in the hood, they are truly underprivileged.
