Steven Cohn, I think our main disagreement is about the percentage of gender-specific behaviors are biologically or naturally based as opposed to socially constructed. I think the vast majority of observable differences in behavior between men and women (or boys and girls) are not inherent differences but instead a result of cultural assumptions about gender roles.

But even assuming you are right about the source and magnitude of differences, I still think the scouts should stop being separated by gender. Will something (boy bonding, a feeling of freedom from judgment, etc.) be lost by making the scouts coed? Probably. But it would also get rid of a lot of negative gender roles currently being taught by the separation, and it would be an opportunity to teach kids healthy understandings of gender and experience interacting with the opposite sex. To me, what will be gained far outweighs what might be lost.
