I read a claim at one point (I believe it was in responce to a comment similar to yours, Wherin the person who corresponds to you in the analogy gave the specific example of coal mining as a dangerous field)

And the claim was that women HAVE had harder times entering coal mining jobs, and for some time in some places were forebidden from doing so. (and that recently at the time of the claim in a certain area they were allowed to have that job.

However, I don't have a source for this, only a vague memory of what someone else said. As such, my memory may be faulty, and what they said might not have been entirely true. I don't know.

This is just something I thought could be potentially relevant.
