What's So Bad About Spam?

Okay, I'm from Hawaii... the Spam Capital of the World. We love our spam here. What I don't understand is why does spam have such a bad reputation? Of course it's not healthy and made with all kinds of leftover sh**, but it can't be any more gross than cheap hotdogs, vienna sausage, luncheon meat, and countless other processed meats.
I think I'll make myself a spam musubi now...lol
