increasing vulgarities

now, there are more and more people who know the 'F-word', the 'B-word', and so on. what was considered rude and offensive to parents is the norm now, in morden day society. so, what is causing this, the internet, seniors from upper secondary, or is it by peers.
the internet is the most likely. if you click here, not that you want to, you can find avid contributers contributing the latest lingos, and also, some vulgarities along with it. since children are very IT-savvy nowadays, these words will circulate very quickly, and the result, a ruder and more vulgar society.
next will be the presence of vulgar seniors. people have a sort of misconception now. which is 'vulgarities are cool'. in a desperate bid to draw attention, they pick up words from the seniors, so that they can show other, 'hey, i know this word and you don't, so i am cooler and better than you. thus, those who are picked on will also try to learn more hokkien swear words, to prove that they are cooler. this cycle keeps repeating itself, till they all learn how to learn the worst of words, such as 'F***'.
lastly, the point on peers, it is very closely related to the above two points. peers will specially search for rude words. they want to make themselves seen, by making others laugh. they will try many means to do so, such as talking back to teachers, cracking racist jokes, and of couse back to our main topic, the use of vulgarities.
in conclusion, the main thing to me is attention. it is the need of attention, that draws out the worst in most.
