I'm afraid that you are the one that doesn't grasp the concept--although it's a different concept. Why do you think that the FCC has forced broadcasters to put the shows with the colorful language or the questionable parts on in the late night hours? It's because anybody and everybody may be listening. It's the same with the ham frequencies as with broadcasting--someone that is transmitting has no idea who may be listening, and the FCC frowns on language like that simply because you don't know who IS listening!
You may think having a 'sewer mouth' may be OK, but if you start with such language in a public place, you would be shown the door rather quickly--and possibly helped through it--by LEOs. Ham radio frequencies--AAMOF, ALL radio frequencies--are public places too, as the FCC has reminded everyone of regularly.
BTW, I like Howard Stern and his antics--but I wouldn't let my kids listen to it when they were younger. If you have no respect for children and with older people who may find that language offensive, the FCC obviously does since they will and do take action against such language and anyone who uses it inappropriately--that is, on the air.
Oh, and if you knew what you were talking about at all, you would know that the repeater in question isn't anywhere near me. Try reading the entire thread before commenting. That way you wouldn't make yourself out to be such an asshole.
