Crudeness is never appropriate; it's a matter of the heart

If behaviors are making women uncomfortable, those behaviors ought to make men uncomfortable as well. Such behaviors aren't appropriate for public venues, regardless of the sex of the audience.

So the issue, then, is not one of changing behaviors to accommodate women, but changing behaviors to eliminate crudeness, period.

Good luck.

Besides, anyone who is coerced to restrict his crude behavior for the sake of females will likely resent said females, thereby having the opposite effect than was intended. Fail.

The things that proceed out of the mouth come from the heart, and those defile the man. So the real issue, then, is one of changing people's hearts. And there is only one true solution to that.
