You've been to university, you should know that the technical terms of specific science fields often mismatch to the popular use of the words.
I've been to college, never been to a university (unless you count physically being inside of one).
But this isn't a "professional vs laymen" use of the term, this is a "laymen with one political leaning vs laymen of any other leaning"
use of the term, much like how Trans means "anyone who isn't a man or a woman" to the far left, while to everyone else we still use it to mean those transitioning from one gender to the other.
Gender studies are no different in that regard, which is why it pays to actually read up on the terms and their connotations instead of just assuming you can deduce them from reading the words without context. This shouldn't really come as a shocker to you.
The only thing that tells me is that those in the politically driven areas of academia don't actually understand linguistics, though given the fact that terms like "homophobia", "transphobia" and "islamophobia" exist despite their linguistic meaning being at odds with their definition, I shouldn't be surprised.
When you keep making up terms that brake the rules of how our language works, why is anyone shocked when the 99% of society that isn't in the group making these terms doesn't know what the hell is trying to be said? If we need a term so badly, why not make one that actually follows the rules of English linguistics? If anything that would make it easier to make new terms to begin with.
