The Christians are called Christians because they worship Jesus Christ and they frankly admit it. The so – called Muslims are calling themselves the Nation of Muhammed and they idolize him, worship the fabricated tomb attributed to him and believe in him as the one who will intercede for them only in the Judgement Day to be in paradise. All of this contradicts the Holy Quran.
We simply call them Mohammadisns to undeceive them not to insult them. The best and the only way of reform is to tell the truth and nothing but the truth.
