Some atheists seem to not want to full-on “hate” fascism, I guess thinking it demeans them or some such. As such their more neutral stance makes them “collaborators” (or worse), whether they realize that or not. And thereby allows such to spread, by virtue of not being opposed hard enough.
Evil needs to be fought against - and I’m not talking some alien lifeform with red skin, a forked tail, and carrying a pitchfork, but inside of our very selves.
But I guess I didn’t express my last point very well:-D.
