Anton LaVey's form of Satanism includes many elements of paganism, almost an anti-Wicca.
Alot of Pagans attempt to hide their religion from their peers as pagans have been persecuted since the early days of Christianity, and as such some tend to have anti-Christian views.
That said, if they are known pagans, most pagans will quite gladly give time to help out people starting out on the pagan path and will talk to non-pagans about their views and beliefs.
Today it mostly means someone who is part of a number of religions that comes under the umbrella term of paganism. Usually these religions are nature-based or revere nature or whose religion is tied to nature in some way.
Pagans come from all walks of live be it politics, law enforcement, education or business etc.
Most pagans mark their calenders by the eight fold year, with four major festivals and four minor. Solstices/equinox festivals are also recognised and celebrated.
