Re: Is it discrimination
I think his point is that it wasn't a problem when the ads were "women only", but only became a problem when someone made "men only" ads. I.e. the fact that it became a discrimination problem is discrimination in and of itself due to why it became a problem. In other words, when the ads were targeting women everyone was OK with it, but now that someone is targeting just men it's a problem.
Kind of like how the U.S.'s Affirmative Action policy was designed to fight racism while being racist itself.
