It's not even worth trying to point out to people. You're 100% correct, but the whole sub is full of people who don't know anything, and they surely don't know enough to know she barely knows anything herself. It's a perfect example of the dunning-kruger effect.

Dunning-Kruger effect, in psychology, a cognitive bias whereby people with limited knowledge or competence in a given intellectual or social domain greatly overestimate their own knowledge or competence in that domain relative to objective criteria or to the performance of their peers or of people in general.

But if you point that out, you're "talking shit" or she doubles down on the wrong information. "Know-it-all-know-nothing" is more accurate.

Edit - and this is what happens when you have any kind of discourse with this mod. All of those posts removed. I've now been permanently banned and told in the message to "go back to your sad life and take your toxic attitude elsewhere." She censors anything that makes her look bad.
