Oh, please do tell me what physiological factors make men more suited to be electricians, I'm sure that will be fascinating.

Well, there's a simple explanation really. Electricians are at a significantly greater risk of many possible adverse physical casualties that men are otherwise better suited to handle. If a man were to, god forbid, die performing one of these dangerous jobs, it would have a much lower impact compared to a woman (due to the inherent disposability of males).

In fact, many jobs that previously involved a level of physical labor that would make them more suitable for men have changed due to the availability of equipment and tech.

I get what you're saying here, however, no amount of socially or environmentally cultivated conditioning would compromise our primitive hindbrain that has existed for millennia. Technology has changed things for sure, but that doesn't mean (that with all other factors being equal) men or women wouldn't be better suited for specific responsibilities.

The point is NOT that men and women are the same.

This is probably the most sensible statement you've stated so far.
