It is true that buddhist monks have involved in political and social activism in the past and recent years involving physical conflicts, the distinction is that these involvements are not made in the name of religion or based on religion doctrines.
Crusades and Jihads are holy wars launched in the name of religion and based on religion doctrines. I cut & paste a passage I found somewhere which gives some backgrounds.
Racism is a defining feature of many of humanity's religions. The Old Testament abounds with claims to the racial supremacy of God's "chosen people," setting aside very different laws for how chosen and non-chosen peoples are to be warred upon, interacted with socially, and enslaved. The master race of the Old Testament was ordered to have slaves, taken from nations around it. Those stories also give us the bizarre racial mythology called today the
"Curse of Ham," a narrative widely adopted in modern white supremacy circles for its robust depiction of Arab, Persian, and African humans as morally inferior. The New Testament's central figure claims of himself that he was sent only to the people of Israel; no other "peoples" are singled out by him in this way. The bad erotic lit of the Old Testament, the Song of Solomon, sets dark skin and physical beauty at diametric opposites, having the narrator of one of its verses describe herself as "black but comely," emphasis added. When the Old Testament says to make war it says, for example, to make war on "the Midianites," never on certain Midianites, or enemy Midianites, but all Midianites - infants to adults, young and old, with the youngest and most nubile kept as slaves.
The Qur'an is much the same. The sectarian God described in it has made a perfect work of Arabic, preferring the peoples therein and taking a bizarrely obsessive interest in the internal affairs of different bloodlines and tribal groups therein; he is as petty a tyrant as he that ruled the Old Testament's tribes, obsessing over the trivial provincial minutiae of the ephebophilic bandit and his people and, like the God of the Bible, having no special interest in others outside that race group but in how to enslave and make war upon them. Allah, the only survivor of Bedouin polytheism to escape the bloodlust of Mohammed's invasion, cares almost as much about relations among the Arabs as he does relations among women.
Matthew 15:24
24 But he answered and said, I am not sent but unto the lost sheep of the house of Israel.
Leviticus 25:44-46
44 Both thy bondmen, and thy bondmaids, which thou shalt have, shall be of the heathen that are round about you; of them shall ye buy bondmen and bondmaids.
45 Moreover of the children of the strangers that do sojourn among you, of them shall ye buy, and of their families that are with you, which they begat in your land: and they shall be your possession.
46 And ye shall take them as an inheritance for your children after you, to inherit them for a possession; they shall be your bondmen for ever: but over your brethren the children of Israel, ye shall not rule one over another with rigour.
Song of Solomon 1:5
5 I am black, but comely, O ye daughters of Jerusalem, as the tents of Kedar, as the curtains of Solomon.
