> How active should men be in actually helping to solve the gender diversity problem

There is, objectively, different representations of different groups in engineering.

There is no objective reason to think that this is a "problem".

Whether it's a problem, a feature, or just an unimportant fact derives from one's value system...and different value systems are just that: different.

To assume that this is a problem - that it's obviously and necessarily a problem - skips past the fact that there are different opinions, and - values being values - no way to prove one set right and one set wrong.

We might as well talk about the "chocolate icecream" problem, or the "punk rock" problem.
