Willow, the autodidact witch on Buffy the Vampire Slayer, said it best (after attending her first and last meeting of the U.C. Sunnydale Wiccan Club):

"Nowdays every girl with a henna tattoo and a spice rack thinks she's a sister to the dark ones!"

and...

"They're just a bunch of blessed-wanna-bes!"

Of course, if you could start fires, translocate souls, and fling HB pencils at 200 miles an hour just by waving your hands, you'd want to say it too...
