Well I don't exactly subscribe to ommiting evidence.. Doing so strips the characters of the abilities and capabilities that we as readers have grown accustomed seeing these heroes perform thus forumlating our opinions of them...
I think any call to BS in concerns with feats is nothing more than a very subjective or bias mindset imposing self-importance over valid evidence.
There are of course extremes that are just past the point of ridiculous... Like if Wolverine punched the Hulk unconcious.. that would certainly be BS.. Wolverine being about as fast as Spiderman though? Nah.... that's just a contradiction to the benefit of the doubt that Spiderman's been given for years, not really an opposition to facts.
