I'd actually agree with Brett here; I didn't personally find their post in any way offensive, they were asking a question. I personally find the question a little bit silly but that's not at the fault of the poster (her experiences growing up were surely somewhat different to mine, and more importantly, I find a lot of student (or prospective student) questions quite silly knowing what I know now, as I'm sure many of mine were at that stage in life to those in my current). I've been in "their shoes" in regards to being ignorant about how things mostly actually are plenty of times. I'm sure I still am about plenty of things, and while I have opinions, I know they aren't necessarily "the right answer."
Being professional in the VT-halls as a student is not the same as ready room banter is not the same as posting (thoughtful, to include questions previously unanswered) discussion on this wonderful site.
And I'd agree that asteriks are not required for "grown-up" words on this site; I doubt any children will get their first exposure here.
If your main point was to be professional in most aspects of your job as a Naval Aviator, then good on you. But there should always be some room for less than that (at least as a JO, when it makes sense), and honestly in the way the question was phrased there was nothing whatsoever unprofessional about the question. Big difference between someone saying "most military women are sluts or lesbians" and "I heard some people say that most military women are sluts or lesbians.... is it true that most people think this?" And if these words alone offend, I hope being told to release weapons on other humans don't.
