lol tbh i see this "ISIS" group nothing related to the religion in any way. They just made up some beliefs and facts of their's about a religion and said "yup that's what the religion tells us to do" when it's really just some bs they made up themselves. This ISIS group is just a terrorist group, they got this stupid ideology in their minds that's completely wrong in so many ways, nothing to do with Islam at all. They're representing a religion that doesn't support what they're doing and that doesn't include the rules they say are included in it.
People who support ISIS should just die, like how can you support a terrorist group, with their fake ideologies and inhumane actions of murder.
