Probably Judaism, but true Judaism not influenced by Zionism. The latter has done to the religion what Wahhabism is doing to Islam. And while many Americans due to their support of Israel cannot distinguish between the two, Judaism and Zionism are not the same thing. Judaism is one of the few religions that does not believe that you need to belong to it for salvation, nor does it obsess over the afterlife but focuses more on the present. And due to being stigmatized for a long time in Europe and the Middle East, Jews--assuming they're not influenced by the atrocity known as Zionism--are pretty sympathetic toward other minority groups. Honorable mention would go to Sikhism. Like the Jews, they are used to being severely persecuted and so are pretty sympathetic and tolerant toward others. While they often get a bad rep for the ceremonial knife and are often mistaken for Muslims, it should be noted the knife was for self-defense from the persecution they historically received and Sikhs have suffered under the Islamic yoke just as much as my kind have. I don't believe that Hinduism and Buddhism are as peaceful as New Age westerners on the internet portray them as. The former was responsible for the caste system and has a strong history of persecuting other religions on the Indian subcontinent including Christianity (which precedes the British btw), Buddhism, and the Sikhs. The latter while not as violent as Hinduism still is not perfect. Buddhists have been known to wage holy wars against each other with spiritual leaders of various disagreeing monasteries lending support. Even the 5th Dalai Lama himself once famously instructed: "[Of those in] the band of enemies who have despoiled the duties entrusted to them: Make the male lines like trees that have had their roots cut; Make the female lines like brooks that have dried up in winter; Make the children and grandchildren like eggs smashed against rocks; Make the servants and followers like heaps of grass consumed by fire; Make their dominion like a lamp whose oil has been exhausted; In short, annihilate any traces of them, even their names." Being Russian Orthodox, I am also biased in favor of my own religion. I would say that Eastern Orthodoxy was pretty peaceful up until the Crusades and particularly the Sack of Constantinople in AD 1204, where strong anti-Western tendencies were sown that led to Russia at least adopting an imperialistic outlook/rivalry with the West, and the rest of the Orthodox world absolutely detesting Uniates. In modern times these prejudices have pretty much subsided, although the general skepticism of the West/Cold War mentality still runs strong.
