I suggest you face the facts. As long as she is in there, she is in the running. She has quite a fanbase, and no, those who support her to win are not "****ing insane", they are just supporting their favourite housemate, like I'm sure you do.
And like Billy said, anything can happen this series - everyone was expecting Victor to go on Friday night, but who actually went? Jade.
So no, maybe you should face the facts, and maybe grow up a little - nobody is mentally retarded just because they're supporting Amy to win/they think Amy can win.
