Using verbal aggression is normally a very poor way to conduct oneself and may speaks volumes of inner-character. However, swearing is not always aggressive, and the spectrum goes from ‘mild’ swearing to ‘very strong’ or ‘raging’. Context is important in determining. Cursing at one’s thumb if found unexpectedly beneath a swinging hammer is admirable. Cursing at another living being beneath the arc of one’s swinging fist? Not so much. Unless of, course, one is simply ‘returning the favour’ (assuming without too bold a dividend)
Swearing at a woman is sexist if you are swearing at her only because she is a female (or trans-female), but not for any other reason AFAIK. As always, mileages vary. Treat each individual with respect. If you (for good reason) believe that they do not deserve respect, then at least keep respect for yourself in any dealings with them.
