Quote:3) There is evidence that Thor is bulletproof and not bulletproof, and anyone claiming otherwise is wrong.
Sure. It's just that the evidence in favour of Thor being bulletproof totally eclipses the not-bulletproof-evidence. There's no way to look at the evidence and reach Busiek's conclusion, unless you pull a Brevoort and selectively dismiss evidence.
Yes, Thor has shown a wariness of bullets, but he has also taken them repeatedly without significant injury. It doesn't take genius to come up with a plausible explanation, unless you don't want Thor to be bulletproof. Don't insult my intelligence by telling me that the evidence supports that position, however.
Busiek and Brevoort rejected any and all attempts to come up with a NO-PRIZE explanation for why Thor has been wary of bullets in the past, and why he has taken them without injury since.
There were several good suggestions put forth.
