Whats the difference between a cult and a religion?

[Last Things]

Failed logic.

Tadpoles do not look like frogs.
Tadpoles becomes frogs.
Therefore a thing that does not look like another thing becomes that thing.

That's not my logic. If you watch tadpoles, they turn into frogs. If you watch cults, they (if they're successful) turn into religions.

However you want to argue it, you are saying that tadpoles become frogs and cults becomes religions. The example of the tadpoles becoming frogs has no bearing on the unsubstantiated claim that (successful) cults become religions. Such a claim requires evidence which tadpoles becoming frogs has nothing to do with.
