Asking for decency in the workplace shouldn’t even be worth arguing about.
For any lib-lurkers out there: it's called your private life for a reason. Whatever consenting adults do in private is none of my business, just as what I do in private is no-one else's business either. (like clean my 30 round mags ;-) But in public, I expect a certain level of decorum and common courtesy for the sensibilities of others.
