Christianity is not a coherent doctrine, but a rather loose collection of beliefs and practices, many of them mutually contradictory. We thus need to make sure that we talk about the US version of it - which is but another nasty identity/celebrity cult, one of many such cults (including leftish ones) that proliferate in this barbaric hellhole.
In other countries (cf. liberation theology in Latin America), christianity played a more positive social role.
