You have never had a problem with from an American viewpoint potentially-offensive images? OK. I have never had a problem with potentially-offensive photos (and text!) on pages like [[female]], [[hair]], [[feet]], [[homosexual]], etc... By saying that only [[penis]] and [[clitoris]] are potentially offensive but not the other examples I mentioned, you are implying that your viewpoint is the supreme one and more important than all others.
I don't really understand what you're getting at here, but I'd like to point out that I'm British, not American.
Sorry, that was a bone-headed slip. I think I menat to say western viewpoint. It is a very natural thing to assume that ones own values are omnipresent. We like to be around people who are similar to ourselves and therefore we by default assume that those that have different points of view are wrong. But it doesn't work on an international project like Wikipedia. I.e what you think is "potentially offensive" may be totally non-offensive to someone else. And what someone else think is "potentially offensive" may be totally non-offensive to you.
