There is a double standard to a limited degree- I can't remember the source of this, but a good explanation I saw described it thusly - it's the difference between "punching up" and "punching down". When a woman makes a joke about a male stereotype, it's "punching up", the classically lower status individual tweaking the nose of those in power. When a man makes fun of a female stereotype, it's punching down, or picking on someone. That doesn't necessarily make it right in either direction or represents a set of absolutes, of course, but it does explain the willingness of people to excuse a certain amount of one type of stereotyping and not another.
