Not sure what else is left to say. All I’ve known for my whole life is most powerful country in the world and its satellite states killing as they please around the world to no consequence. And this ability to kill and oppress worldwide is the supposed testament to their greatness.

I saw that we're doing another round of Twitter discourse on here, so, not to beat a dead house:

Twitter is still a Nazi cesspool, with a paid CSAM service. We can collectively choose not to be involved with that.
