I was in the same boat as you: indeed Christians in Asia lean politically left even when they are pro-life. They will be literally shocked to see the Left in the West are all post-modern secular humanists. I think many socialists may use prooftexts or misinterpretations of Bible teachings to sway many uninformed Christians to support a lot of political Left platforms.
Take social welfare as an example: hard surveys of effects of years of unlimited and unconditional social welfare has shown they don't help people. Yet Christians continue to support them contrary to survey results just because of some misapplications of a couple of verses of Scriptures. Where we go from here...I don't know.
