were they vegans??

I got the impression they were eating meat pies in the pubic hair scene. And looking up traditional Swedish Midsummer dishes, there seems to be an emphasis on seafood, such as pickled herring and smoked salmon. Potatoes are popular as well.

One woman specifically said she was making "meat tarts", so no, they weren't.

I don't know if they were vegans, but They were cannibals. They ate one of the victims (meat pie) and if you count menstrual blood and pubic hair too...and likely piss from the looks of the drinks.

The whole cult is based on the circle of life and renewal. Makes sense. Released at a time when nations are already trying to brainwash us into accepting soylent green as a staple diet.
