Who said they didn't? Hispanic men are great.
And why should these many positive qualities be necessarily seen as intertwined with viewing women as objects? (which is what sexism essentially is) Not all men who have these positive qualities (Hispanic or not) are sexist.
Who said it was? No offense but you really seem to love impulsively throwing random things around that no one ever said and assuming things about people based on whatever preconceptions you have. (FYI, that's not what a forum discussion is for, you have to actually read and try to understand what people are saying as opposed to randomly throwing stuff around and making random assumptions about other people. If you don't want to do that, then find another way to express yourself, no point in wasting your time (and others') here.)
So women who are not attractive are doomed to never hope any man will really, truly enjoy dancing salsa with them? What about unattractive men?
In other words, why bother with intercultural exchanges since it's all pointless because no one will ever truly understand another culture if they didn't grow up in it?

Once again, way to assume that everyone is as limited in their ability to understand and be perceptive to another culture as your friends or whoever it is that you have in mind when you say this.
For one thing, coming from another culture can actually allow someone (assuming they have a certain degree of perceptiveness and cultural sensitivity) to actually understand more about a culture than someone who grew up in that culture, simply because they have multiple frames of reference. Have you never witnessed a discussion between people from different cultures in which someone makes an observation about someone else's culture and that person says "Wow, I never looked at it like that since to me that seems "normal", but now that you point this out I can see it is true". I've seen these kind of discussions happen a lot--of course, they generally only happen when people have a certain degree of open-mindedness, both with regard to other cultures and their own.
