Just like no Jews were killed in the concentration camps?
Strawman arguement... Please give me documented proof that people are sent to camps in Vietnam for simply being Christian. Sorry, it does not happen. There is plenty of proof of Nazi prosecution of Jews.
I know personally some who go to Vietnam to work among the underground church and death or re-education is the norm for believers who are caught or just sometimes accused by someone else. Documented proof? Are you tuned into the real world? How, get access to offical files or maybe we should contact the free press in Vietnam? Nuts!
Please define 'underground church'. There are Christian churches all over Vietnam where people worship without any interference from the Vietnamese government.
