Neo-Paganism is usually assumed to be some LARPy middle class hipsters dressing up as Druids, carrying out some fake and over-elaborate, obviously concocted ceremony.
Needless to say, that is not real paganism, as there is almost nothing authentic about it, and there is no genuine faith in whatever Gods are mentioned or supposedly invoked. It is quite likely that true faith is not even possible in a modern society.
But, still, there is such a thing as Neo-Paganism.
