Good to know that you at least admit misogyny is a problem.  But since we're talking about a very, very small number of additional votes Clinton needed to win, I think the point is that misogyny alone could have been enough.

For example, in these states, Trump won by:
Michigan: 10,000 votes of 2.6 M cast (16 electoral college votes).
Minnesota 43,000 votes of 2.7 M cast (10 EC).
Pennsylvania 44,000 votes of 6 M cast (20 EC).

If any more than half those voters had gone the other way, Clinton would have won the electoral college and been president  -- ie, 50,000 votes.

As for 50 other countries having elected female leaders, that's nice, but they have all been the exception to the norm of electing male leaders.  Also, zero countries in North American have ever elected female leaders, and we're not even close to electing half female legislators either.  Heck, even Trudeau's appointing half women to cabinet has resulted in many fragile male egos who just can't stop howling about it.
