Of course, it’s completely subjective what is the biggest violation. The constitution itself doesn’t really make any distinction between which violation is worse, unless I am misremembering something.

If you’re offended by a lack of due process and racism and that sort of thing, you might also find the Internment of Japanese Americans during WW2 similarly offensive. 2/3 of them were US citizens whose only “crime” was being ethnically Japanese. Or the infamous Trail of Tears.
