It's absurd how this people don't know absolutely anything about linguistics. "Men" in menpower doesn't mean "the power of men". It means the power of people. Words can have different meanings when written in different contexts, even more when combined. Go on, downvote, be like the many preachers, iconoclasts and witch burners of the past, see you in ten or maybe a little more years when we can focus again on stuff that matters for mankind.
