No, you are basing the fact of his action on behalf of his nationality, which is South Vietnamese.
You said.
You basically based all his post, his view and his opinion down to the fact he is the South Vietnamese Boat people, he act the way he act here because his people were defeated by North Vietnam. And hence he harbour the grudge of North Vietnam, Communist and to some extend, China.
Let me give you a "For Instant" not all South Vietnamese harbor grudge to North Vietnam. Or not all former South Vietnamese officer are pro-South Vietnam and anti-North Vietnam.
Did you even know
@Viet father used to serve with the South Vietnam armed force? I don't think he harbor any ill-will against Vietnam today and North Vietnam.
Many people coming from South Vietnam does not harbor anything, as my mother told me before, most of them actually hate their own government. And in fact, many refugee escape Vietnam is no other than the Chinese Ethnics North Vietnam national that won the war in 75, but was force to leave Vietnam by the Government in '79. My mother included.
