Basically, only evangelical fundamentalists make this kind of general claim, and then not all of them. The people most guilty of the claim are those who tell everyone else that they are going to hell for not following their version of Christianity, which, when it comes right down to it, is "another Gospel" because Jesus never put anyone down like they have.
