Mutants - Born with X-Gene and is hereditary. AKA Homo Superior.
Examples: The X-Men, Magneto, Sabertooth, etc.
Mutates - Superhumans who acquired their superpowers by exposure to some mutagenic compound or energy (either accidentally or deliberately)
Examples: Spider-Man, Hulk, The Fantastic Four, Daredevil, Captain America, Deadpool, etc.
Regular people - The general public in the Marvel Universe.
For the cases of the Fantastic Four and Captain America, the general public knows how they came to be as that information is more well known. But for the cases of Spider-Man, the Hulk, or even Daredevil, their stories aren't known, yet they aren't labeled as mutants by the general public.
Why aren't Spider-Man, the Hulk, and Daredevil labeled mutants by regular people?
In the Spider-Man films, it's shown that New York City citizens have come to accept Spider-Man, even helping him at times. At worse they may consider him a menace based off the newspaper the Daily Bugle, but they don't fear/hate him as if he were a mutant.
How do regular people in the Marvel universe come to accept one (mutates), and abhor the others (mutants)? How do they distinguish between the two?
Have any Marvel stories addressed this?
Obviously for the case of the Hulk, no one wants to be around him-- he's generally not a welcome sight when he's angry.
