If you add show/hide tags to [[Muhammad]], how long do you think it will take for the edit war to start on [[Clitoris]]? I'd give it about 3 hours...
Let them, I say. Our editorial quality will not be ruined if articles are structured in such a way that you have to click a button to see a photograph of a clitoris on [[Clitoris]] - nor will it be ruined if you have to click a button to see a photograph of a jackdaw on [[Corvus monedula]], not that I can see anyone caring about that. (Made to look a little sillier, mind you, but then we do plenty of that already!)
You've completely missed my point. I didn't say "How long will it take for someone to add show/hide tags to [[Clitoris]]?" I said "How long will it take for the *edit war* to start on [[Clitoris]]?". I'm not making a judgement on whether or not the images should be hidden, I'm pointing out that without a policy, we're going to get edit wars, and those *are* inherently bad.
