Denialism is an irrational response which refuses to accept true situations despite overwhelming evidence. Denialism takes the form below. 1. * I personally would prefer it certain facts were not true. 2. * Therefore I assume those facts aren't true. An example is denying the validity of arguments against Christianity or whichever other Religion is the person's favourite. Denialism can take many other forms like denying Global warming. In other cases, people who believe other Supernatural or paranormal phenomena may continue to do so, despite lack of evidence to the defense of the claim.
