I could just delete your comment, but I think the public good is better served by my leaving it in place - so that people can see what an apologist for a cruel, immoral and fraudulent cult looks like.

The Merriam-Webster online dictionary lists five different definitions of the word "cult."[15]

1. Formal religious veneration
2. A system of religious beliefs and ritual; also: its body of adherents;
3. A religion regarded as unorthodox or spurious; also: its body of adherents;
4. A system for the cure of disease based on dogma set forth by its promulgator;
5. Great devotion to a person, idea, object, movement, or work (as a film or book).

All five of those diffinitions can be applied to the Cult of Scientology.

The same definitions could also be put along side other mainstream religions.Please explain.

Well, yes they could. Thats because, within the english language, cult is a word that can be used to describe any set of religious beleifs. It is not intrinsicially an insulting term.

Their are other definitions for cults, which are more slanted to describe the organisations that most people think of when discribing a cult.

One such example would be the B.I.T.E. model. Again, scientology does fit within these definitions.
Scientology engages in Behavior Control, Information Control, Thought Control & Emotional Control. It does all of them, on many levels.

It also falls into Older definitions, it behaves as a mystery cult, with degrees of initiation and the slow revilation of infomation over time.

It is a cult BY EVERY definition i can find.
