I Love Men; I Abhor “Man”

Why do we continue to assume everyone and everything to be male until proven otherwise? “Man” invented the wheel; “man” discovered fire; “mankind” gave us history; “mankind” destroyed the earth. All myth! If men actually were responsible for all that has gone before, who do you suppose birthed them, married them, gave them children (of both sexes)? If a man discovered fire, don’t you suppose he would be the one expected to hang out in the kitchen?
