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.
No they weren’t sent to the camps for being merely Christian. But the Catholics in the south were just about all pretty seriously anti-Communist and for that many Christians got sent to the camps. The few Catholics that remained in the north were not trusted much and their social and economic lives were pretty circumscribed. The new commie government did start to re-educate the Buddhist monks and bonzes, but that didn’t last long. The Buddhists all just sort of went home and poured tea. The country just about stopped and the government declared the traditional Ways, Buddhism, Daoism, Confucianism, to be Vietnamese Cultural Identity and left the Catholic clergy straitjacketed or chased them out of the country. The last anti-Catholic disabilities and rules (there is no Law as we know it in a Communist system)were officially removed last year. Catholics are still not party members but there is no ban on them in the military now.
