The point of the cartoon is that the "feminists" who scare some people are really straw feminists - i.e. a fictional construct created to support an argument, rather than something that exists in the real world. And that it's as sensible and mature to be scared/wary of them as it is to be scared of monsters in the cupboard or ghoulies under the bed, which are just as real.
I thought it was a bit ho-hum and long-winded, though. Sorry. But YANBU to love it if it speaks to you.
