I think it's because students tend to either trust the academic hierarchy, or understand that they need to adhere to what they're being taught in order to pass the course. When I was studying biology as an undergraduate, there were a number of religious students who vehemently disagreed with evolutionary theory, but would work under - in their minds - the assumption of this fiction being true in order to get decent grades. The same may well be true of students being taught that woke gibberish like "egg parent" and "sperm parent" are the correct terms to use. Or they just accept it as technical jargon as they would with all the other domain-specific language used in their course.
