WhingeBobShitPants you are teetering on the cusp of smug.
Swearing in earshot, or even in a non-abusive manner towards children, isn't abusive. It's common.
In both senses of the word.
my best friend's dad Effed and Beed and C'd constantly, loudly and at length, about and towards anyone who was anywhere near him. I adored the man and so did his children. Agentler man you coulndn't hope to meet - but he was a builder, and builders are, um, 'salty'.
my dad never once swore at me, and my friends were petrified of him to the point where not one person visited me at home throughout high school.
Swearing does not = abuse. Abuse = abuse.
I think the people squealing that swearing is abuse are people who would have to be pushed to the point of blind rage before they will swear at their children - so they perceive people who do swear to be constantly at the point of blind rage. This is not the case. A good natured-but-weary "ohhhh you little fuckers" is a good deal less damaging that an icy cold, seethingly rage-filled hissed "you have made mummy very, very angry, children..."
