yup, that's pretty much it. a fanatic is a person who is borderline obsessed with what ever insanity it is they are peddling, weather its religion, politics, view points. i prefer the word zealot. they love bringing it up and just want to argue with you about it and force the view on others. zealots will go to the end of the earth for no reasons other tan thye love to argue for some reason. true zealots are religious or lawers
