The terrorist groups that have arisen today are the same type of people that popped up time and time again throughout history, the khawarij. They were the first deviant sect to pop up and they resemble the very terrorists that we see today. Throughout history the main Islamic body took up arms against them, fighting them until they gave up. They were people who acted upon their own desires and stated that spilling the blood of innocents was lawful and they pronounced takfir upon Muslims who committed major sins, and would murder them unlawfully. They rose up against the early caliphs and rulers of the Muslims and rebelled unlawfully. Muhammad called these people "the dogs of the hellfire". They prayed excessively and seemed to be the most devoted Muslims, however they made that which was unlawful lawful and distorted the religion. Jihad was declared upon these people and for 1400 years they have popped up and have had to be beaten back. It is a mistake to equate these people with the mainstream salfiyyah movement as the two groups are at war. It is hard for Americans to distinguish between these groups because they may seem very similar. Only people who are grounded in the religion can easily distinguish between these groups. The reason, as the sheikhs of the salafiyyah explain it, is that the khawarij and other deviant sects of Islamic groups have grown and became out of control because the main Islamic body has stopped waging jihad upon them. These terrorists (ISIS, Al-Qaeda, etc.) and deviants groups have declared war upon the House of Saud and Saudi Arabia as a whole. The mainstream salafiyyah movement as well as Saudi Arabia has declared war upon them as well. Hamas, the Muslim Brotherhood, ISIS, Al-Qaeda, Shiites and all other deviant groups are enemies of the mainstream Salafiyahh movement who aim at reforming Islam as a religion. People caught funding these groups in Saudi Arabia are incarcerated. The sheikhs in Saudi Arabia feel that the Saudi government and the royal family haven't been proactive enough at destroying these deviants sects.
My point is there are very different Muslims, ones that hate terrorists more than any American, because they believe these deviant sects are distorting the religion and destroying it. And they believe it is their duty as faithful Muslims to preserve the religion at all costs. They have no interests in attacking countries that are not hostile towards them. They do hate the western way of life because they believe it is full of sin a corruption, however due to the religious tolerance towards Islam they do not consider them enemies that are to be violently attacked. They are taught to spread the religion of Islam in a tolerant way by calling people to Islam and educating them about it. Any hatred they have towards the western way of life (which they believe is full of sin) is not meant to acted upon but rather they are told to engage disbelievers in a humble, respectful manner, in a way that they may encourage them to embrace the religion. Now when they preach and educate fellow Muslims, they do express extreme dislike and disapproval for the sinful behavior of disbelievers. They are taught not to befriend disbelievers, but they should make sincere attempts at calling disbelievers to the religion.
