I, like you, come down on the side of evolutionary biology/psychology. I don't go with just my gut or experience.

Facts are facts and research is research, even when (scratch that, *especially* when) we don't like the results.

It's always important to keep in mind that while society can technically override biology to an extent, it's much, much more likely that society will simply exaggerate our natural biological tendencies.

It's not society that teaches men to like large breasts, but it IS society that reinforces and exaggerates the desire. It's not society that reaches everyone to like clear skin, but it IS society that reinforces and exaggerates the desire.

Same story with the role of men and women. The root of our interactions IS based on genes and evolutionary history, but sure, over time people can distort, exaggerate and take advantage of the relationship and interaction. Maybe I'm biased but I think that's the more realistic and productive view, rather than saying it's ALL genes or ALL society.
