foul language is a subjective term. what you consider foul, i might consider acceptable. when i was a kid, my parents tried to keep me from using the word "sucks" like that sucks,then they'd yell at me so i would say fuck shit piss ass cock balls pussy something like that and they stopped yelling at me about using suck.
if you try n tell ppl one word is bad, then some other word is gonna offend you later on and ur gonna try n ban that word too until you cant use any unpleasant words or words that represent something unpleasant. we need cusswords just like we need all other words, and isnt hacking and cheating the same thing?
