Islam is a newer and more progressive religion than Christianity. If Islam is not compatible, then Christianity DEFINITELY isn't, either.
Some FOLLOWERS of Islam are less progressive than some followers of Christianity, but there are also followers of Christianity that are less progressive than some followers of Islam.
You can't destroy Islam. There are almost two billion people adhering to Islam. How are you going to convince them to become atheists or turn to another religion? What would convince YOU to switch to another religion or to become atheist?
