parody and satire

i think that parody and satire laws should depend on the content of the parody/satire and that the author/publisher should have a say. i think that if the parody/satire is very offensive or is insulting to a person/group of people then it's not ok. the original authors/creators should be able to ask the website for it to be taken down. but i think that anything that can be considered harmless fun, that is not offending or insulting anyone, should be ok but the creator should credit the original authors/creators. also parody/satire shouldn't be allowed if the person borrowing material is getting some type of monetary benifit from it.
