These are common CCP talking points, in fact primarily devolving from Chinese sources, which seek to turn Tibet into a nation in need of saving by debasing it into barbarism. Whatever half-invented, invented or factual casus belli the invaders invoked, half a million Tibetans were marched last year into work camps by CCP occupiers. [1]
In terms of historical accuracy, I stand by my claim: the Islamic and Christian faiths each hold a history of violence that squarely puts Buddhism at the top for peace. I do not deny the violence by the Buddhist Brigade and other factions proclaiming Buddhist faiths in Sri Lanka and Burma happening today but on the historical whole, no major faith comes closer.

This is very different from policies that attempt to control the entire world, from the US, the USSR and some European powers. By and large China doesn't care what you do in your own country, unlike the USA.
Also, Tibetan Buddhism is VERY FAR from the "most peaceful faith on the planet". The reason why the Chinese were able to take Tibet so easily is because the Buddhist elite were incredibly brutal with the majority of the population, with widespread slavery and massacres. They were absolutely hated. It doesn't justify their seizure but we don't have to whitewash one of the most horrific political systems for it.
