Mostly attention issues. She had her big hit, was very famous then that started to fade so tried a dozen different things to stay in the lienlight from bad sequels to bad prequels to publishing bad stories under a fake name, but none if it got her enough attention. So she did what basically every other washed up celebrity does and just be controversial to get attention.

And also I think part of it is that rich, steisght white women, are very privileged but being a woman gives them 1 point in the oppression Olympics so they think their opinions on these issues matters more. Which is why almost all the most outspoken term are middle class strisght white women.
