Alright, let's power up the bass cannon here.
First and foremost, temporary society honestly has desensitized us enough towards cursing that it's accepted almost common place.
Growing up I remember if a movie said the f word once it would automatically get an R rating. Now adays you can watch a regular TV show on primetime television and hear a variety and plethora of four letter words.
Myself? Do I swear? All the f*cking time. I don't swear because I'm desensitized towards peoples feelings, or that I am rude, I swear, because it's a part of the culture I'm in. Specifically the military culture. We all swear copious amounts. For some reason, trying to get your point across using adjectives other than f*cking just doesn't work. For instance, tell private joe snuffy to clean his room, he would be like yea, pfft. As opposed to, PRIVATE, CLEAN YOUR F*CKING ROOM NOW! That gets the sense of urgency and the fact that you will not put up with his bs. I know the modern day military is trying to shift away from the profanity, but it's just never going to work out, as there are still too many of us left over from the wars before the hearts and minds military came out.
Do I notice when someone swears around me? Quite contrary, I notice if someone isn't swearing around me, and usually again, due to the military culture we make fun of them. Poke prod and joke. But if you guys think I have a foul mouth, head on towards your nearest Army or Marine Corps base and go visit any infantry company, and see some professional guidance from their First Sergeant. He'll really, really impress you with his vocabulary. Usually consists of 27 F words to three to four non swear words.
