That's an awful broad brush you're painting with, there. While as a man I can laugh at ads obviously targeted at the reptilian portion of my brain, that doesn't mean they're not necessarily effective. I mean, I don't buy any Axe-brand deodorant or anything, but that doesn't mean I find it easy to turn away from their commercials (I'd argue that as a 28 year-old married man I'm not their target demographic, anyway).
