I think you may have quoted the wrong thing. The section you highlighted above states that clothing was fumigated with the same gas later used by Nazis to exterminate prisoners, it makes no mention of it being a way to “medicalize” or make exeuctions “humane”.

That came after these experiments on the Mexican border, id encourage you review the history of execution methods in the US, heres a good video on it but feel free to research it, you will find im right.

Again, I’m not American so I’d appreciate it if you highlighted how this is related to “American Liberaism” which you initially criticised. As it is it appears you’re assuming whatever actions the someone in power in America takes is “American Liberalism”, I’m not sure that’s something I agree with.

Liberalism is the dominating ideology in America, its the one that instituted aperthied and slavery against black people, deported all the communists and climbed to the top of the shit pile that is US politics; you only vote for one of two neo-liberal parties in America, so calling it 'American Liberalism' in reference to americans actions is accurate.

As it is it appears you're assuming whatever actions the someone in power in America takes is "American Liberalism", I'm not sure that's something I agree with.

The poles of American ideology are theocracy/Christofascism and liberalism. Virtually all of what the state does that isn't theocratic is liberal.
