This is a very personal one and something that I understand whatever side of the fence someone may sit when it comes to language.
For me personally it's never been an issue. We had very few rules or restrictions when the kids were growing up in terms of age appropriate content and my language is a disgrace generally speaking. The main, major rules we did have was never to take the piss, push their luck too much and always assume that others don't like and won't want to hear, see or talk about the same stuff we do freely at home. Husband is the epitome of an old fashioned gent and seldom uses language and the very few times he has chirped up and put the fear of God into anyone it's been to groups of young lads really giving it the full effing and jeffing and being vile about girls.
Here nothing is off limits and we live and thrive on a household filled with language, insults thrown back and forth and oddly enough neither of our kids ever really swore until their late teens. They understood that swearing is not something they can or will ever do outside the confines of our four walls and even now in their early 20's, they don't even use words like “bloody” or “crap” out and about in public because they hate hearing other people swearing and being crass out in public, grew up mindful of others and have always been respectful even when using the worst language at home.
They are the most respectful, kind, honest kids with a moral compass that puts me and most others to shame which is ironic given the lack of rules and restrictions we had. I remember when they were very little sat in the back seat of my car singing along innocently to “Rage Against the Machine” I had playing and when I turned it off and went “Kids... you're not in trouble and haven't done anything wrong but that word – you can't sing or say that word it's really upsetting to most people OK?”
My daughter asked by they're called “Curse” words one day almost thinking aloud and my son who has always been a mad historian chirped up that it dates back ages to Medieval beliefs that using those words cursed people and caused ill health, the plaque and other unpleasantries and my daughter was “Really? Cool so where did this come from then?” Pair of them – both in primary school so very young and they were sitting there discussing the origins of swear and curse words like literary professors 😂
The main difference for me is not being sworn at Neither has ever uttered even a mild swear word in anger or temper but I will not tolerate being spoken to with attitude that's disrespectful, being muttered and mumbled about and I will not tolerate anyone swearing at me.
Kids are so mindful of language / grew up to have such respect they don't even use mild swear words when we're at the house of their Grandma who died earlier this year. They have accidentally said the odd swear but immediately “Sorry Grandma sorry sorry sorry!” cos it feels wrong to speak like that in her house.
It's not something everyone will get or agree with and each to their own but the swearing and listening to dodgy music or movies / video games doesn't create the problems it's the understanding and respect they have around its use.
Funniest thing for me anyway is the very rare time my daughter pops a button over something at work or Uni and from the second she gets in the car or through the front door she unleashes this intense torrent of the foul mouthed, raging torrent of abuse that would make Gordon Ramsay blush.
It's not offensive though it's more just brilliantly effective because she reserves it for special occasions 😂
