I'm sure you have hard or even said some of those things. We heard those kind of things or variations often. You can play dumb if you want, but the message is clear to everyone involved.

In fact, the "is a nive guy, you should give him an opportunity" is so common that originated the nice guy TM stereotype. And let's not start with the self diagnosed "autist" who happen to be disagreable and ignore boundaries with women, but not with men. Then you would have people saying that women *need* to be understanding and patient because asking for basic respect is "ableist" acording them.

So to answer your question, it is common and ubicuos. Done by many people that doesn't consider that they are doing it. Now be honest, have you ever told a woman or girl to "give an opportunity" to a guy that you think is nice, cool or whatever but that she rejected? If you have, then you have a more concrete answer: you.
