Jonah Goldberg is determined to outdo himself in the category of dumb:

I find Darwin fish offensive. First, there’s the smugness. The
undeniable message: Those Jesus fish people are less evolved, less
sophisticated than we Darwin fishers.

The hypocrisy is even more glaring. Darwin fish are often stuck next to
bumper stickers promoting tolerance or admonishing that "hate is not a
family value." But the whole point of the Darwin fish is intolerance;
similar mockery of a cherished symbol would rightly be condemned as
bigoted if aimed at blacks or women or, yes, Muslims.

He’s right about the undeniable message.  But I don’t think it’s saying what he thinks it is.  For evolutionists, the fish represents the connection between life in the sea and mammalian life.  According to their story, God ordered the fish to rise up from the sea and walk on earth, so that, eventually, the fish would become man (without the God part).  This is an alternative to the literal creationism of some Christians which has a couple of different stories each involving a sea.  I would even venture to guess that many Darwin fish cars are owned by Christians–many of whom are dedicated evolutionists. 

The ridiculous thing about Goldberg’s remark is the charge of hypocrisy.  The point, obviously, of the Darwin fish is to insist on scientific evidence over the unsupported factual assertions of a religious text.  The evolutionists, in other words, challenge fact with fact–the literal creation story (which for some reason very many Christians believe isn’t true at all).  Many Christians do believe this story, however.  They believe it with such a vengeance they think it ought to be taught as fact in science classes in place of or at least alongside of the evolution "story."  In some places, they have even succeeded in undermining the teaching of evolution on the grounds that it’s just a "theory."  That view, of course, is absolutely preposterous–and ignorant and intolerant of basic scientific knowledge. 

Here’s the really dumb thing. To believe in the literal truth of Genesis in the face of overwhelming scientific evidence is not the same as being black, female or Muslim–unless being those things involves embracing obviously false assertions about reality.  To believe in the literal truth of Genesis (and the sometimes consequent belief in the immorality and falsity of evolution) is not even the same thing as being Christian.
