Yes, if you could give us the examples, that would help us answer your question.
I would most possibly do the same thing, or take the south back to US as brothers, but I might also add a little punishment. The punishment would be limited import for a period of years (1, or 5). I would also not allow them to vote or participate in any political meeting, congressional decisions, etc.
Hope this helps, you might have a different opinion however, but as I think, it would be better to punish them for
1. Not obeying the rules (still having slavery)
2. Electing a secondary president.
3. Helping the war happen.
4. Trying to become independent from the rest of US.
The Vietnam War faced mass opposition for several reasons inlcuding:
1) Unfair draft practices- Many citizens who were affluent and had connections were able to avoid being drafted by the US military. This resulted in a majority of the soldiers being individuals from lower-middle class socioeconomic groups. Many citizens felt that this was unfair, an dubbed Vietnam a rich man's fought that happened to be fought by the poor.
2) Monetary cost- The Vietnam War cost America billions of dollars over the course of the 2 decades of their involvement in trying to keep South Vietnam out of the control of the Soviet Union/communism.
3) Casualties- The US military suffered over 50,000 deaths due to this war. Americans felt that this was unacceptable.
Asian Americans faced discrimination no matter if they were Chinese, Korean, Japanese, Mongolian, etc. Discrimination towards immigrants had applied with the American superiority complex that started all the way back from Manifest Destiny. This discrimination was also due to World War II propaganda of Anti-Japanese sentiments which then over casted on Asians in general.
