I define cults as religious doctrines that are not completely biblical or overtly anti-biblical.
Do you have another, objective definition that would cover Islam that wouldnt apply equally to other religions that have been widely accepted now or in the past?
See above. Read the Bible and then go read the Suras.
Tell me then that they refer to the same moral code.
Bet you can't.
I have no problem with your definition, as long as you don’t try to force others to agree.
You do realize that something around 90% of the world’s population is a member of a cult by your definition, depending on how rigidly you interpret “biblical?” (I’ve known some people who interpreted it very strictly.)
Also, by the definition posted earlier, “a religion or sect considered to be false, unorthodox, or extremist,” most of the world probably considers you to be a cult member!
