i think we need to talk about some words.
what is the difference between saying
that was so cancer and that was so horrible. Cancer is something bad? really bad? don't you agree? So when you say thats was cancerous you basically say that was fucking really bad. it not like people with cancer feel bad when people say something. bad is like cancer since cancer is bad. People used words like demons and devil back in the days, but now when we all not actually believe in such shit and no longer are brainwashed by pedo priests, things like aids and cancer is our times demons and devils.
The word cancer or AIDS in its self is nothing wrong. Its what you trying to say with your words and not the words in them self its wrong. Some people say its the same to say "fucking cancer" as to say "fuckign gay" So according to them gay=cancer? which means they either think cancer is not a bad thing or they think gays are as bad as cancer.
