I have not heard of this story before, but it does hold some truth.
As some people put it, blood is thicker than water.
For some reason, Hmong Christians have no real respect or tolerance of the people who has yet to convert. For every one non-convert who bashes against Hmong Christians, there are three Hmong Christians who are bagging against those who has not converted. This has cause some deep divided in families bounded by blood.
When a non-Christian attend an event they are a bit more respectful than Christians when they attend a non-Christian event. When Christians pray non-Christians do not eat, but wait quietly with everyone else. But, when asked to kneel or eat Christians exclaimed that it is against their faith.
I find it strange that Hmong Christians have so much they can't do, but the Americans have little or no restriction and has done everything that non-Christians has done. Can someone elaborate on this? Can this because Hmong Christians are still fairly new to the faith and so they have to be on their best behavior?
