Ah, well then, let us by all means treat the past as an entirely alien country and learn nothing, ever.
However, there is nonetheless a reason the US bombed South Vietnam harder than North Vietnam. Any regime has some supporters or it doesn't last a day; with massive outside support, the South Vietnamese regime/s lasted for a few years. But they certainly never had enough local support that they would have lasted long without US presence even if the North never made a move. Still, yes, surely there were some people who were supporters or implicated in the regime and might have wanted to leave on that basis.
But I think it's awfully facile to say "Person X ran away from a place that had been bombed to smithereens and poisoned so nothing would grow. He must have supported the people who did it!" Most refugees from Vietnam were refugees from war, not political refugees, and the war's destructiveness to civilian lives came mainly from the US.
Y'know, Ho Chi Minh was originally friendly to the US. He assumed that the place with the original war for independence from foreign colonial rule (British) in the name of freedom, who spent so much of their time talking about freedom, would support his people's aspirations to independence from foreign colonial rule (French) in the name of freedom. He was mistaken. Accounts suggest the reality came as something of a shock to him.
