1) They don’t believe in equality.
The film maker’s free speech is immediately disqualified and the woman attempts to no platform him because he doesn’t agree with her politically and is a white man.
2) They don’t believe in free speech.
The woman tries to impose her own authoritarian code of conduct on the man in order to silence his First Amendment rights.
3) They’re racist.
