From PZ Myers:
If you’ve ever been to a national park (or to most state parks), there are strict restrictions on what you are allowed to do as a visitor: you can’t back a pickup truck in and load it up with petrified wood, or an assortment of cactuses, or harvest a crop of squirrels. There are all kinds of rules to protect the status of the park from predatory hordes of visitors — if you go rafting through the Grand Canyon, for instance, get used to pooping into a can because you have to haul out everything you bring in.
This is true for everyone. You don’t get to say “Back off, man, I’m a scientist” to excuse going at the Grand Canyon walls with a rock hammer. You have to get a scientific collecting permit, and it’s no rubber stamp process — your application actually gets reviewed by qualified peers.
You know what’s even less effective? Saying Back off, man, I’m a creation scientist.
