Actually Wicca was created in the 60's
And is not a nice fluffy religion.
You probably got you hands on some Llewellyn books. They stripped it down and made it into what most neo-pagans want.
Makes me want to vomit.
If you are seriously interested on finding out what Wicca is go to

The site is fantastic! And funny as hell.
As for religions being "the right one".....
That is completely subjective.
Especially since it is all just a way of understanding a concept.
