Writing the 900th SQL query is not hard science, it's engineering. And every engineering discipline, to my knowledge, has a large gender gap in participation. So, it is not necessary to "establish either that CS is somehow fundamentally different from every other hard science".

As I've pointed out before, that shortcut doesn't work.

If we just look at the higher level computer science your jobs, then again we will see that in the most comparable field, mathematics, women underparticiate something like 30-70.

If we ignore all that and pretend working with computers is uniquely bad for women judged against comparable careers, can we start calling out the enablers yet?

Well, bad news, there's another hurdle to jump, which is that female participation in computing is inversely related to a country's ranking on gender equality tables. I've yet to see that stubborn fact integrated successfully into the argument. It is mostly just ignored.

And that's off the top of my head. There are probably more. It's a complicated question to answer. So you must demonstrate at least familiarity with the obvious hurdles before questioning the moral worth of the people who disagree with you.
