Sam Shamoun was properly rebuked by Dr. James White. (see video below)
Just saying again, because it needs to be said again.
Sam needs to repent of his sinful anger, bombast, name calling, and bad witness to Muslims, and violating 1 Peter 3:15 (violating the “with gentleness and respect” part) and Ephesians 4:15. (violating the “speaking the truth in love” part) and also violating “do not return evil for evil or insult for insult” (1 Peter 3:8-9) He does the opposite of this to anyone who disagrees with him and turns on them. I tried to encourage Sam privately by email, to stop this method, but he has refused to heed the admonition of Scripture.
Sam Shamoun has had lot of good material at his blog and at answering-islam.org and at www.answeringMuslims.com, when he sticks to issues and reasoned argumentation, and uses the texts of the Qur’an and Hadith and history and the Bible, etc. and quotes from theologians, but many times he laces his interaction with people with lots of pugnaciousness (constantly fighting back and quarreling), name-calling, ad hominem, sinful anger, bombast, and snarkiness.
Sam needs to repent, because his witness is a bad witness and all the Muslims are using his anger and bad behavior to drag Christ’s name in the mud.
It is out of love that we rebuke you, Sam. Repent of your pugnacious spirit. (see 1 Timothy 3:3 and take heed to 3:7 also)
1 It is a trustworthy statement: if any man aspires to the office of overseer, it is a fine work he desires to do.
2 An overseer, then, must be above reproach, the husband of one wife, temperate, prudent, respectable, hospitable, able to teach,
3 not addicted to wine or pugnacious, but gentle, peaceable, free from the love of money.
4 He must be one who manages his own household well, keeping his children under control with all dignity
5 (but if a man does not know how to manage his own household, how will he take care of the church of God?),
6 and not a new convert, so that he will not become conceited and fall into the condemnation incurred by the devil.
7 And he must have a good reputation with those outside the church, so that he will not fall into reproach and the snare of the devil.
1 Timothy 3:1-7

Qualifications for overseers/elders/pastors – the same goes for missionaries, evangelists, and apologists.
