Are by far the bigger enemies of Islam.They are truly Satan's agents in disguise.Why? Because due to their evil and misguided actions, people around the world actually believe that perhaps what they claim is true, and that Islam actually condones their deviltry.
This will then drive people away from wanting to know the truth about Islamic teachings, and causes them to intentionally and/or unintentionally discriminate even those Muslims who condemn the evil themselves.
We as Muslims face many trials in our lifetimes but the trial of these monsters claiming to be of us is truly an enormous tribulation indeed!
But I believe as long as we fight against them, and do all we can to spread the true word of God minus the misquotations and lies, these demons will not triumph.. at least not all the time!
