There's also another side to this whole discussion:
What about those of us who identify as being of the other gender, or not having one at all? Example: a guy who identifies themselves as female, and prefers to be called "she", but still wants to play a male character... how do we suddenly know this and correctly gender a person?
The answer is, we can't.
@OP: Correctly gendering a player, by assuming they are the same gender as their character, is not always going to result in correctly gendering a player. If it bothers you, you have to inform the other players who are (more often than not) innocently just applying a generic case.
