There's no doubt that cursing exists in every language but the question here, for me, is who curses the most?! I don't know! What I know is some Canadians curse a lot and telling dirty jokes is not off-limit! Funny thing is they say Canadians are very polite! I think they are but perhaps when compared with Americans! It's hard to say unless you have interaction with many nationalities but when I say many nationalities I'm talking about the major ones, of course. Not any shitty, tiny piece of land who calls himself a country! Here, in Canada, you could be at work, in a party, listening to the radio show or watching something on television and people curse like it's a normal activity of the day and tell dirty jokes in front of women, children, elderly, everyone! That's the culture!
What's interesting in Western culture is they use the things that they like the most to offend others! One of the most popular(!) ones is the word co*ksucker! Fellatio is a normal act between two people who have sexual relationship, in many cultures but Westerners used that as a curse although they, even some men(!), are in favour of it, madly! I never understood this! Pig is the animal which is not consumed in many countries, particularly the countries with Muslim majority as it is forbidden to eat. Though I've never heard in any Muslim, Arab or generally Eastern culture using the work pig as an insult! Americans, mostly and Canadians and British, as well, use that word very frequently as insult despite the fact that they love pig! Pork Chop, Bacon, Pulled Pork, Sweet and Sour Pork, are all meals that people consume in the West, and then the poor pig is used as an insult!
In Asia a few other animals are used as an offensive word: Cow, Donkey, Mule and Sheep, are mainly used to insult someone! Another animal which is frequently used as an insult is dog! I know it will drive Westerners wild as a dog is a member of the family but that is the fact although some countries have changed in the past couple of decades. Koreans and Filipinos are dog-lovers but when it comes to eating them! They have been changed recently in the past few years as now they think having a dog as a pet is a sign of affluence and being Westernized! In Western Asia Dog-father and Dog-Mother!(!) are both an insult which indicates that the person's parents are dogs or at least one of then is a dog! While dogs are considered loyal and helpful animals to human beings for decades, it is not know why this poor animal is used as a curse word in those cultures. It could be the fact that dogs are considered filthy and dirty in Muslim faith! It makes no sense to Westerners but they use that although having a dog as a pet, these days, as I said about the other side of Asia, is considered a sign of being modern and Westernized! I think debate over the subject could be longer than this. I just wanted to have a hint.
