That artwork makes a good example of just how untenable the position of Pagans is today in the United States. All it takes is a few self-righteous people deciding that what you believe and what you stand for is immoral, indecent, or unholy, and you could lose everything. The Christian system of misinformation and subjugation isn't working so well on a society that is, per capita, perhaps the most widely educated society in the history of the world. People now see clearly how corrupt the institution of Christianity truly is. Too often the Jim Bakers and Jimmy Swaggerts of the world condemned us for our wretchedness, only to be revealed as more corrupt and twisted than we ever dreamed of being.
People are tired of being condemned by hypocrites.
And they are looking elsewhere for real answers. Religions predating the oppressive Christianity are immediately appealing. There is some debate as to how old various Pagan paths are. Wicca, for example, is clearly not much beyond fifty years old, though it IS based on very ancient religions and concepts. Druidism is clearly much older, though even it has not survived through a direct lineage, but has been, rather, rediscovered through ancient manuscipts and archeological evidence.
