Do you think the Soviets should have run around slapping random people who used to be in the Wehrmacht? Do you think throwing your milkshake at some German who supported Hitler in 1932 would have stopped the Nazis?
Punching random goons achieves nothing for the people. It is not praxis, it is not a revolutionary action, and saying you support it doesn’t suggest that you take actual steps to oppose anyone.
You say “same kernel as Arch,” but Arch has five officially supported kernels, and you can choose any of them while you build your system. EndeavourOS allows you to switch kernels, but it’s assumed you will install the latest mainline kernel and you are only given LTS and Zen as additional options.
If you use LTS or Zen, or especially if you use Hardened or Real-Time, vanilla Arch is a different experience re:kernel.
