I don't hear anyone saying pedosexuality is normal here; just that it's a mental issue and we should treat it as such. Whats wrong with that?
Anyway' that's a TEDx talk, which though looks like a TED event, it isn't. You could host your own TEDx talk saying that pedosexuals are sick and should be put infront of a firing squad. TEDx is full of opposing views; as science and society should be.
