She was an extreme anti-war leftist. She went to North Vietnam by choice. No one made her go. By going there, as a famous American, she gave aid and comfort to our enemy. The details of her visit does not change the fact that she went there. But, the details do add to the seriousness of her crime.
I wouldn't want to live near her grave. That's gonna be one stinking place.
The SOBs are anything but anti-war. They are anti-US military, pro-revolution. They never met a leftist uprising they didn't support. They worship monsters like Mao, Stalin and Castro. Hard to be "anti-war" with heroes like these.
