Hmmm. Don't an awful lot of Christians believe the same thing about Christianity?
Obviously, some followers of Islam present serious problems in our world today, but I am not convinced that there are not a good many moderate Muslims.
Islam, Christianity and Judaism are all branches of the same tree and worship the same God--a fact that Muslims are much more aware of than most Christians.
Painting all Muslims with the same brush is not at all constructive or helpful in my opinion.
So, without further delay...
Cheers...
