If it's ok for religious people to advertise their religion with bumper stickers like the fish symbol, for example, then it's perfectly ok for an atheist to state that religions are fiction, regardless of who gets offended.

I for example, find the bumper sticker of people supporting the NRA offensive, so what? Am I going to be expected to remove anything anyone might find offensive? There would be nothing left, as anyone at any time may find something somewhere offensive. This is a ridiculous politically correct notion.
