What are opinions of why some Twilight fans are so violent towards people who don't like Twilight?

Most twilight fans, like me, get OTD. (Obsessive Twilight Disorder.) It's when you are so obsessed with Twilight you start to hate people who hate Twilight. You also get sick if you don't do anything that has to do with Twilight over a short period of time.

people who don't like twilight honestly don't give it a chance. everyone i know that dosent like it hasn't read it or seen the movie. at first, i thought it was stupid but i saw it and honestly got OTD the very first time i watched it :)
