My fervor against creationists is anything but religious.

But it is fervid.

Not all strong emotions are religion.

IF I am infuriated by idiocy it isn't religious.

If I am impatient with willful ignorance it isn't religious.

If I mind people's ability to think being undermined by their own education (or lack thereof), it isn't religious.

It isn't ritualized.
It isn't dogmatic.
And it isn't based on a supernatural explanation.
