Despite being a regular church-goer, occasional preacher, and self-declared freelance theologian, I've never had the urge to badge up my car with a Jesus fish.
Partly this is because I don't want to be a bad witness and occasionally I get in the wrong lane and have to cut up a random stranger and in those moments I'd rather not have them thinking "not only is he a hoon, he's a Christian hoon!" I base this on my own tendency to think people with Jesus fish should drive better than they often do - and I don't want to be judged by my own high standards.
However, I don't have any issues if people want to adorn their cars with Jesus fish. And I quite like some of the other fish that have appeared in response. Cathy spotted a car near our house recently with two such responses stuck on the back.
Now this one, I've seen before and I think is quite funny - it's the good old Darwin fish, complete with legs.
This one on the other hand was new.
Yes, that's right. It's a dinosaur eating a Jesus fish.
I guess the point is that the existence of dinosaurs is awkward if you're the kind of person who believes in a six day creation about 6,000 years ago. Dinosaurs really do eat that theory alive. And it's a small step from that to dismissing any religious story as nonsense disproved by science.
But who's to blame for that erroneous step? The only reason people make that step is because there are some Christians who claim that unless you believe the six day creation version of events you can't believe the rest of it either. So when someone can't believe that, they assume the rest of it is nonsense.
