I went to Vietnam a couple times. If you hang out downtown in the city, you might get a random Jehovah's Witness or Seventh Day Adventist* try to chat you up. "Oh, we can't do missionary work out in the open, so we just do one-on-one conversations like this". Despite the lack of "Jesus saves, die sinner" signs in Hanoi, you can definitely find Catholic and Protestant churches in Vietnam.
The Western press likes to piss and moan about settler nation missionaries that go, without proper visas mind you, to spread their Western versions of Christianity to the DPRK, only to get deported. So am I allowed to enter a white people country without a visa to stir up trouble and expect no consequences???
I'm the furthest thing from an expert on Myanmar. I get everything I know from Burmese friends. But if you look into the minority people situation, many of them are being heavily proselytised by the worst of the Amerikan type. I don't want the Pat Robertson's the world anywhere near struggling people.
*I'm definitely not saying that JWs and SDAs are anywhere near the worst as Christian sects go.
Many adults cling to Christianity because it can function as a crude coping mechanism in an uncaring society: the appeal of a higher power caring for someone is easy to see, and religious institutions in general can be convenient sources of community, especially for somebody trapped in an antisocial culture like the United States of America. I am irreligious yet I feel more comfortable revisiting a Presbertyrian church than approaching my own neighbors.
Liberation theology is not a desperate attempt to fit a square peg in a round hole. For some Abrahamists, it simply feels natural or logical to them. I am willing to agree that theology of any sort is unnecessary for emacipating oneself, but it is—at best—a waste of time trying to convince somebody to discard it since they are already on our side and their spiritual beliefs are harmless. If their beliefs remain a big deal to you, though, then you need to understand that they are symptomatic and that addressing them directly would be the wrong approach to take.
Yes, the Church has frequently been complicit in colonialism. Yes, aggressive proselytization is always wrong. Nevertheless, we also need to acknowledge that many lower‐class Christians have rebelled against their oppressors despite mainstream Church teachings, and that they are reluctant to let go of their beliefs since they are convenient sources of comfort, not necessarily because they are worried about retaliation. Religion is a double‐edged sword. The ruling class has used it as an instrument of oppression, but that does not mean that it has never backfired either.
