The analogy is a stronger country being attacked by a weaker one with the additional context that liberals tend to be critical of Israel's apartheid in Gaza. Liberals are hesitant to be critical of Palestinians fighting back, as they are also a little more hesitant to be critical of women hitting men. Maher is being slightly critical of the liberal bias in both cases. The analogy is good, and not at all misogynistic.
Wow. Thanks, dude on Facebook!
