It’s also what you mean by feminist. The definition is that you believe in equality. Now what does equality mean? For some that does mean that the man goes to work and the woman raises the kids but that both jobs are equal. For others it means that either gender can do what they want and should be honored for that. Both are views of equality but are not exactly the same. Added into this is that today’s world is not what it was thousands of years ago.
When heavy back breaking labor was the norm along with a need to be super aggressive I don’t think that many woman would be welcome or want to be in those jobs.
