Because Ben Shapiro makes the mistake of correlating religious fundamentalism with forgeted-up stuff. Him trying to "do the math" by adding these statistics together is like petty first-grade math that only idiots like Ben Shapiro would push. Not to mention that his whole spat about "well, as an Orthodox Jew I understand the violent stuff in my religion" shows he's contradicting himself (or as Shapiro would say "GETTING DECIMATED BY HIS OWN LOGIC") because he tries to justify his religion and all the hateful bigotry alongside lambasting another hateful religion. As an agnostic/skeptic, it's funny watching Judeochristian guys try to attack Muslims when they still pretend their religions don't preach dumb stuff as well.
Quran (2:191-193) - "And kill them wherever you find them, and turn them out from where they have turned you out. And Al-Fitnah [disbelief or unrest] is worse than killing... but if they desist, then lo! Allah is forgiving and merciful
2:190 Fight in the cause of Allah those who fight you, but do not transgress limits; for Allah loveth not transgressors.
9:5 But when the forbidden months are past, then fight and slay the Pagans wherever ye find them, and seize them, beleaguer them, and lie in wait for them in every stratagem (of war); but if they repent, and establish regular prayers and practise regular charity, then open the way for them: for Allah is Oft-forgiving, Most Merciful.
8:65 Prophet! Rouse the believers to wage war. If there are twenty amongst you, patient and persevering, they will subdue two hundred: if a hundred, they will subdue a thousand of the disbelievers: for these are a people without understanding.
4:76 Those who believe, fight in the cause of Allah, and those who disbelieve, fight in the cause of Satan. So fight you against the friends of Satan. Ever feeble indeed is the plot of Satan.
3:168 -Consider not those who are killed in the way of Allah as dead. Nay, they are alive with their Lord, and they will be provided for. They rejoice in what Allah has bestowed upon them of His bounty and rejoice for the sake of those who have not yet joined them, but are left behind [not yet martyred] that on them too no fear shall come, nor shall they grieve. They rejoice in a grace and a bounty from Allah, and that Allah will not waste the reward of the believers.. (it's good to die for allah)
The Tanakh documents violence, the Quran encourages it.
