The NFL custom jersey shop isn't so liberal as the stamp makers evidently, they have compiled quite the naughty list--sort of:
This rather bizarre conclusion is reached when trying to order a personalized jersey from the NFL Shop, the online merchandise site run by the league. Anyone trying to buy a jersey with the single word "GAY" or "LESBIAN" or "GAY PRIDE" on the back gets a rejection message that states: "This field should not contain a naughty word."
The wording was changed in the hours since this article first appeared and the NFL contacted. Now when you enter "GAY" and try to checkout you get the following: "The personalization entered cannot be accepted." This wording is no less offensive than "naughty" and doesn't change the issue. Especially when you can buy jerseys with "FAG" or "DYKE" or "HITLER" on them.
The project manager was showing off the functionality when it was first developed and I bet him I could get an offensive jersey order through in less than two minutes. I won the bet and it's the reason ‘smegma’ is on the list.
The mural of approved and verboten jerseys is a work of art in need of a grant!
