'Luckily you don’t have to agree with anonymous posters on Mn. People behave very differently in rl.'
You think people are not being truthful or...?
I talked about this with DH last night. I am very sweary and he is not. He doesn't seem to mind other people swearing, but he can't bring himself to do it. Like literally can't. I tried to get him to say fuck once and the best he could do was a mumble 
He said that he noticed ages ago that his workmates (male dominated outdoors job) stop swearing when he goes into the office 
On our team we are very very sweary. I've learnt some excellent new words and phrases from a Scottish colleague. Such a turn off phrase! Today was awful and having a good inventive sweary meeting or 2 really helped us feel like a team, somehow.
If someone joined who didn't swear it would change the dynamic and the existing people would swear less.
That's how things work. Different people behave differently with different groups and people and situations. That's fine and good.
The other thing that occurs to me is there's a class and where you're from element here. What it a standard word in Australia is a definite swearword in USA for example. I notice the anti swearers never responded to that point. Unless I missed it.
It's all a bit hyacinth bucket tbh. Not swearing is a very old fashioned lower middle class aspirational type thing isn't it?
