Actors are only typecast in the minds of people who are too lazy or stupid to separate the actor from the character (s)he portrays.

Not really. Good way to turn it around and blame the audience, but that isn't very fair. Some actors really are typecast to certain roles. Why? Because they play the same sort of role over and over again. Is that the audiences' fault that they have a hard time imagining that actor in any other role, when that is the only kind of role they have seen them in? Hardly! If an actor doesn't want to be typecast, all they have to do is branch out a bit. You see some actors and are blow away at their ability to do different things, and then you hear Jim Carrey/Adam Sandler have a new comdey out, and decide to skip it because you have seen the last five movies he has been in and can barely distinguish one from the other.

It is not the duty of the audience to not be "lazy" or "stupid" and suspend their belief that this character played in the same way by the same actor as a character different movie are two entirely different and unique individuals. If and actor is worth his salt he will convince you of this, regardless of your level of intelligence or your incentive to work at convincing yourself.
