I assumed quite a few things. If I guessed correctly, then:

Telling somebody that they are not good enough to talk to because of not knowing how to do that is cruel because it gives them no escape, since they can’t change their past, and can’t catch on since you won’t talk to them.

A constructive way to address the situation would be telling them something more rude and direct, but also less humiliating, like “I didn’t ask you to do that”, “I wasn’t talking to you” or just telling them to fsck off. Just imagining what you’d say if it were a girl behaving this way and reacting accordingly.

That quote doesn’t simply lose gender roles in conversation, it uses them to say that the other side is inferior in that regard.
