Well, I don't know what your culture says about dating, and I won't ask out of respect because I know you asked for it to remain anonymous, but I think that as long as two adults, that is anyone above the age of say...21 or thereabouts, can make their own decisions about those they want to date. Love knows no boundaries, or so they say, though I have yet to experience it myself, so who knows what this "love" stuff is really about. Or even if it even exists. So yeah. As long as the age difference isn't too terribly big I don't see a problem with it.

I see where you're coming from though, and maybe discussing this subject with your brother in a calm neutral setting, like a coffee house or something, might be the best way to go. Tell him you find his views offensive and would rather he not express them while around you.

He does have a right to his views though, no matter how skewed they are, as an American citizen. So you can't just expect him to change what he thinks because you said it's wrong. That's the whole reason this country was founded. To allow people to have their own opinions and views.
