You can be a genius and a misogynist at the same time, like Dostoevsky, Nietzsche, and Rousseau; the two conditions don't cancel each other out.
But being a "good" man is a measure of how you personally treat your fellow human beings. If you hate half of them, then sorry, you fail.
And I would imagine most men don't appreciate your efforts to make them all look like douchebags.
