So, does it bother you or not? Because it sounds like it does for you to say it's stupid, all caps and backwards.
It actually doesn't bother me, because I think people can believe what they want. Similarly I don't think old school Hmong are stupid for still believing and doing kev cai qub, or others doing kev cai tshiab, or other Hmongs being atheists.
If that family thinks it's appropriate for them to do that, then cool. It might be a symbol of them leaving kev cai qub and doing something new, or it might be what they now believe, or it might be just their opinion and not part of their new belief.
