I don’t think it helps that much on a larger level.
To take your example of religious persecution, I don’t think there’s a meaningful historical trend there. The most infamous religious persecution in Chinese history was Daoist persecution of Buddhists, but China’s relationship with Buddhism was complex; several emperors were predominantly Buddhist, and Tibetan Buddhism in particular held huge sway over the court at times (also over steppe peoples). This doesn’t really map cleanly to modern treatment of Tibet’s religious institutions in my view, besides the general desire of every government to control religious sources of power. (see: Church of England, Oda Nobunaga vs. Enryaku-ji, Saudis and Mecca, etc.)
There was a degree of Christian persecution as well, esp. later on when it became identified as a tool of Western power, and there’s a degree of Christian persecution today as well. But is this a meaningful continuity? Consider three culturally similar countries: China, Korea, Japan. All three historically persecuted Christians for basically the same reasons. Can we extrapolate the same modern behavior for all three? Of course not, the actual outcome was heavily dependent on what path the country followed into modernity. South Korea is ~30% Christian, Japan is ~1% but not persecuted, North Korea is negligible and strongly persecuted, China is ~3% (officially anyway) and somewhat persecuted.
