How have religious fundamentalists groups impacted the world

   Religious fundamentalist groups impacted the world because others might of been treated unfairly due to their religion. Another reason is that other religions didn't celebrate other holidays due to their religion. Sometimes, other religious people would plan attacks on special buildings ( ex. Twin towers) because they feel as if their religion is not being treated fairly. (If you need more help, tell me more about what you don't understand.) I hope this helps!
