Well what codeblue said. I think the Pokemon example is invalid by the way, the reason you're embarrassed to play it is because it's a franchise aimed at kids, and that fact has nothing to do with it being Japanese... So it doesn't really help Jaxjag's (pretty stupid) argument.
The DQ one is debatable, I don't really see why it would be embarrassing to play.
The Bayonetta example is fine, but Mass Effect and Dragon Age both have ridiculous sexualisation too (although not quite so over the top, but still, some pretty embarrassing stuff in there) and they're western made.
All in all, you and Jaxjag are generalizing, and that's just a pretty dumb thing to do.
