I think she is an example of a lot of today's younger people that are convinced they are outraged about something that they won't be in 15 years when they grow up and learn how the real world thinks.
They are told things when they are younger and since they lack experience then they are single minded and focused beyond the ability to think or say anything except that one thing. Their youth also gives them energy and emotion that hasn't been tempered yet so they are border irrational. Kind of like when you're young how you laugh hysterically at dumb shit and when your heart is broken it's like the end of the world.
Younger people also learn what they learn online mostly. So they search out and find, whether it be honest and factual or not, exactly what will feed them. They don't have the capacity to consider other opinions or options either.
I also think she is encouraged and pushed by people who want to use her to push their agenda and see her nothing more than a tool to be used.
And like most kids today, they want to be internet famous and will do anything they can to feel it. And to feel as special, unique, powerful and intelligent as their soft parents have been telling them are since birth.
I think she is a misguided and ignorant fool. Ignorant as in she is just a kid, she doesn't really know anything at all.
