He's very rude. Unfortunately some men feel like it's their birthright to pass judgement on women, especially when it comes to giving unsolicited advice on what women 'should' do in order to be more attractive to
them men. I know I bang on about the patriarchy a lot, but it really is the heritage of the patriarchal system where women were/are regarded as property, and under certain obligations to be attractive (physically and otherwise) to men. It's like how you see men yelling at women on the street that they should lose weight, get a boob job, dress differently, etc. etc. This example is totally different from that, of course, much more mild and polite, but it still comes from the same belief system. Some men are so entrenched in these old-fashioned ideas they genuinely think they are helping and are shocked when women don't appreciate being told they'd need to lose weight, or change their "popular" interests, in order for him to want them!
Personally I would probably have a non-eHell approved response - one liberally quoting from Kate Bornstein and bell hooks - but objectively not I'm sure not responding is the most sensible option.
