Whats the difference between a cult and a religion?

[Zidneya]

I was going to give this answer but thinking about it a lot of cults have become religions relatively quickly, mormons for example and scientology although I myself view both as cults in general they are though of as religions.

Ironically the reason why I ask is because I heard a christian claiming that Mormons are a cult way below Christianity. Because he said christianity is a true religion claiming that there is a clear difference.

I just told him that I don't see any difference at all.
Christian myths, Mormon myts, Christian fanatics, Mormon fanatics, Christian preachers, Mormon preachers. Since none have any evidence of their deities for me all religions are simply glorified cults.
