He has never been a professor. And its certainly news for me that it is prohibited for males of highly regarded position to ask out females (which aren't dependent on them in professional or any other capacity and he's not doing it in a workplace or in other inappropriate environment).

Why not? What's bad in asking a female student out? Is it some sort of crime for males to date females? Is it something only low-level males not occupying any positions allowed to do? It is bad if someone tries to use their power to coerce a female to a date, but if he just asks, and the female is not dependent on him in any way and is free to refuse if she doesn't find him attractive - what exactly is the problem here?
