I like you as a poster a lot, too, so let me say this as nicely as I can without trying to sound in any way offensive. You are right in saying I have been using evidence to make a judgement. That's how you establish facts. You use evidence, which is why I am able to so confidently say what I've been saying is a fact. The evidence backs it up. There are certain essential things that define what something or someone is. In the case of Venom and his origin, Spider-Man is that. You're a Spider-Man fan, you know that. Take him out of it, you do not have a valid interpretation of that character for the simple reason that you have just taken away one of the major elements that defines who a character is.
That's not an opinion. That's a plain simple fact. If it wasn't, you could make any kind of inane changes to a character, call them Spider-Man, Batman, Venom etc and say they're valid interpretations even though they go completely against the material of the character. I can't fathom a rational explanation supported by any evidence that could defend that.
Its why characterizations like Halle Berry's Catwoman is so widely called CINO - Catwoman in name only.
