Heresies and Definitions

Inspired by a conversation at Pro Ecclesia, I started thinking up some modern responses to ancient heresies. 'Tis a shame that heresy is fashionable nowadays. What answers would you get, if you asked folks about:

Arianism - "Those are the 'White Power' dudes, right?"

Pelagianism - "Isn't that a disease?"

Montanism - "Rock climbing addiction."

Donatism - "Giving stuff to charity."

Antinomianism - "Umm, they want to be anonymous?"

Modalism - "Insisting on ice cream with pie."

Adoptionism - "Adopting too many children."

Marcionism - "Believing in aliens."

Nestorianism - "Homes should only be made out of twigs?"

Anyone else?

New additions, and more modern heresies:

Monophysytism - "Say that again, I didn't catch that. What? I still don't get it."

Calvinism - "A quote from the comic strip 'Calvin and Hobbes'." [as opposed to Far Sidism]
