You don't get it. I don't compare. It is not that is worse than that. China attacked Tibet and conquered their Land. I don't need to compare this to the US. I don't care if Country XYZ says it was good. Evil is Evil is Evil. Pull yourself away from comparing. You don't have to weigh Evil against each other.
EDIT:
They pick one side and argue and justify away the crimes “their” Side has done.
You are doing exactly that. You try to argue and justify the annexation of Tibet. You could easily say “Yeah, that was not okay. China invaded and occupied Tibet, this is not okay.” But instead you are trying to compare this to the US and bring up other Countries and what they think. THIS is exactly what I meant.
