"The dislocation involved in switching from one passion to another--even its very opposite--is less than one wold expect. There is a basic similarity in the make-up of all passionate minds. The sinner who turns saint undergoes no more dramatic transformation than the lecher who turns miser."
-- Eric Hoffer --
from The Passionate State of Mind
Essentially it seems that people who are passionate about something are much the same, be it sports, politics, religion, music, wine, or anything you can think of. It's only the object that is significantly different, not the emotion or intensity, for they are quite similar. Is a fight between the supporters of two athletic teams any different really than a fight between supporters of two political philosophies or two religions?
Or at least that's what it seems to me he's saying.
