Buddhists in Tibet have been involved in perpetrating atrocities, both against each other and individuals of other religions. The historical context reveals instances of violence and oppression within Tibet, including the feudal serfdom system that subjected serfs to harsh conditions and exploitation by their owners, who were often monks and aristocrats.

Moreover, the involvement of Buddhists in violence is not limited to Tibet but extends to other regions as well. For example, during the Cold War era in Southeast Asia, Thai Buddhists were complicit in anti-communist mass killings under a nationalist ideology that aligned with Buddhism's principles. This involvement in political violence highlights how Buddhism has been weaponized by political authorities to consolidate power. The history of Buddhist violence underscores the complex relationship between religion and politics, showcasing how religious beliefs can be manipulated to justify or incite acts of aggression. Some notable examples include the mass killing of Ajivikas in India, the violence in Myanmar against Muslim Rohingyas.

I guess what you were trying to say was that Buddhism wasn't as powerful as Christianity to reach the scale of Crusades.
