If you dont then nothing is being required of you...Maybe, just maybe, the majority of men on here don't hang out with fellas who would behave in a misogynic way towards women.
Also, if anyone gets unwanted comments from a drunken stranger in a public place, the best thing to do is not engage, as that risks escalating the situation.
But sure, it should be the responsibility of the person being abused to ignore the abuse, rather than on the abuser not to abuse.
