I know this is a Muppet forum but I think you guys are worrying way too much about Elmo and Kevin Clash's career, and less about his (apparent) pattern of befriending teenagers and (apparently) entering sexual relationships with them once they're adults. (Assuming there is at least some truth to these allegations, and based on Kevin's statements, there appears to be).
I'm a children's book illustrator and a puppeteer and I also (this is shocking) have had sexual intercourse. But I knew, even before I was married (which I am now) that I couldn't do some things that, technically, are legal - that doesn't make them a good idea, or, even morally right. I could not hit on 18 year old girls in college classes that I was speaking to as a guest lecturer, for example.
Kevin Clash's life story was incredibly moving and inspirational. Being in his position, with the respect and attention he garnered, he had a responsibility to himself and his employers to exercise better judgment, and he does not appear to have done so. And I don't say this lightly - after the first accuser recanted, I thought the whole thing was a setup from the start. But a second accuser? And Kevin Clash admitting that "something" went on with the first guy, consenting adults or not?
It's just weird. The whole thing is weird. I'm sad about it, and I'm disappointed in Kevin's conduct, as a role model to puppeteers and children. It's possible to do good work on the one hand while pursuing, well, let's call it "self destructive" behavior on the other hand (look at Jimmy Savile for example). They'll replace Elmo and Sesame Street will go on, but for me, the most disappointing part is that now his whole inspirational story is tainted.
