Just watch the documentary on our Boot Camp and you will get a real good idea of how "polite" we are with recruits..We do not suffer fools...we do not baby recruits...and they are not entitled to be called Marines until they complete all of recurit training and graduate.
Yes, Women Marines are persistent. You cannot be a wallflower or a timid individual and survive let alone succeed in the Marine Corps. By the same token, respect and courteous behaviour is expected.
