“did Lincoln “attack his own people”?”
That would probably be closer to the truth than what is being kicked around here. These were a group of people who would not consider themselves “his people” nor would he consider them “his people”. They were staging violent oppostion to the government in a struggle for indedpendence over a long period. He gased his own people? No. He gased some people that were fighting his control of the country and collaborating with the enemy.
Of course our government would never deploy gas on civilans, women and children, of our “own people”, attack them with armoured vehicles and subsequently burn them to death just becauce they were at odds with the government. That would be crazy to think that we would ever treat our own people that way.
