Depends on if it was a group who got approval to invite the speaker and how much an institute of learning values the idea of views that don't conform to what are seen as acceptable mainstream views.No, but you do get to protest. And if this protest gains followers and the school board decides to turn the speaker away as a result, then I don't really understand your issue with this. The speaker is there for the students and if the students vehemently object then that is that.
Now I'd like to think an institute of learning would want students exposed to new ideas to help them with critical thinking (which actually has a meaning and is about self examination of your own ideas and beliefs and the evidence for them and if they hold up). Considering how the advancement of knowledge has in the past been held back by the orthodoxy banning questioning or investigating I'd have though learning institutions would be very much keen on new ideas.
As an example if we we're using the idea of objections to things based on orthodoxy (in this case not the church but the actual field) I'd never have had a guest lecturer telling us about his loop polymer research which many others in the field believe is some hoax or screw up in his data and his work is impossible. But he got to lecture us and brought his results to prove it. Results many others in the field just refused to look at.
Honestly don't think it's ever been used that way before.By the metric through which "cancel culture" gets applied, which is typically 'when I say so', yes. "Cancel culture" is a meaningless term.
