I normally wouldn’t consider a 14y/o for a senior position. I wouldn’t consider a child to run our armed forces either.
It is you who put women and other minorities into that group with this comment of yours. You are the one to compare being underage and in middle school to being on the same level of a woman.
Your original comment suggests you come from the software industry, in which case you know full well that there are programmers who have been at it for a few years who can program circles around those who have been doing it for 10. Not everyone progresses at the same rate. Years of experience across a wide population will provide positive correlation, but is not anywhere close to being an accurate measuring device and says nothing down at the individual level. To discount someone with less years of experience than your arbitrarily chosen number before you have even talked to them is the very same lack of inclusion being talked about.

I get it. I don't think a 14 year old looks suitable for a senior role either, but looking past that is the point. You never know what someone can offer.
