Was that really so bad? She played a video which could easily be called anti-trans, she had to explain her use of the video in her lesson plan to the university's administration, and that was it. She wasn't arrested, she wasn't even fired. Fascism would be that the government arrests her for speech, not that she kinda maybe sorta might lose her job at some point but probably not.
The reason she's considered a far-right figure now is because she invited Faith Goldy, a literal Fascist, to speak at her university. Is that fair? Probably not. But in Western society, certain ideas are considered so bad, that anyone who presents them in a neutral setting is going to be seen as just as bad. Fascism is just one of those things. If she invited a speaker who wanted to legalize rape, she'd be called a rapist, even if she never raped anyone.
