::::: Given that the image is illustrative, then it's ommision DOES make the article less informative, unless you can find a suitable replacement. And if you check the article The_Last_Judgment_(Michelangelo) you'll find that, OBVIOUSLY ENOUGH, sodomy is not, in actual fact, being portrayed as the punishment for sodomy  rather, sins and virtues are both being portrayed. Weather Michaleangelo thought that anal fisting was a sin is irrelevent  the image portrays anal fisting for sexual pleasure.  
 ::::: (as an aside, in the abscence of any actual imagry of racism, i'd consider a black guy being lynched in a non-racist way to be better than nothing, although obviously some actual racism would be better. I have actually looked for CC pictures of fisting, but can find none). 
 ::::: i'm going to put the picture back in. If you disagree, I suggest one of those 'request for commentry' thingumyjoggers to get some other peoples' opinions
