Hey Bigots! If they invented a shot to cure s from being ignorant- would you take it?

Why do bigots think queer=sickness? Are they really that egocentric that they have no introspection at all? Because if they did, wouldnt they realise that they need to send themselves off to a rehabilitation camping trip in order to be able to retrain themselves to be empathetic and considerate human beings? But seriously - do you truely believe that if someone is gay, they are evil; Is there any reasoning or thought behind descriminisation? please explain.
