Yet if I put a picture of a gerbil against a cloudy
sky in the article on
gerbils, nobody would say "clouds are irrelevant to gerbils" and take the
picture out until someone removed the clouds from the picture. Relevance
isn't enough; offensiveness matters.
It's not just relevance, it's prominence. The clouds wouldn't be
prominent in the photo, they're just in the background. A person
engaging in "gerbiling" would be very prominent. The fact that some
people could be offended by it is irrelevant. A photo of a building
with a small gerbil just visible in front of it wouldn't be acceptable
either, because the building is too prominent and the gerbil isn't
prominent enough, but it's certainly not offensive (unless someone's
religion is anti-buildings, which wouldn't surprise me...)
