there ARE no differences between boys and girls
If anyone is saying that, they are clearly idiots. The internet has copious data regarding the differences between boys and girls. Even after eliminating the porn sites, you end up with various physiological and psychological differences. We're very different in general, the extent to which and whether it's nature or nurture will no doubt rage on for the rest of our lives. There is absolutely no reason to think men and women are the same...
The question of equality is where they are asserting men and women can perform the same. Until evidence exists to the contrary, we have to assume this is true. This is not to say that men and women will do the same things to establish this equality, or will acquire knowledge or even perform the function identically. Only that in the end they will produce the same results.
to create curriculum specifically for girls, who are no different than boys
Accepting the above, which I believe with conviction, this then falls apart. However, where I would direct my nerd rage is at the conclusion that lead to creating a gender specific curriculum as a solution. It must have been something like "CS education as it exists is incompatible with female psychology; a CS education program which can target both genders is impossible, ergo we need to fork a new curriculum". I can't imagine the kind of data that existed to justify this. If it did exist, it seems like a likely assumption than the genders will probably require dedicated education on other topics as well, and maybe we should go back to having boys and girls schools across the board.
Personally I think the problem is entirely social and cultural, and we're wasting our time with this stuff.
