Look up the definition of "Boy" and you'll figure it out. It's not girl scouts, adult scouts and so on. As a den leader, you are not the Cub scout nor the Boy scout. 

You're not making a strong argument for your position. Somehow, you equate wanting boys to have something they feel is theirs alone, as boys, is a result of insecurity. I really wasn't off on your judgment of others. 

I don't share your view the Boy Scouts has to be inclusive to everyone. BSA cites dropping membership, in which they're not reaching the one group they should be, and this doesn't improve it, in my opinion.
