No, justice wasn't served because without marches, he would have got a lesser sentence and even with that, he got away with just manslaughter. That is exactly the point. You claim to talk about fact while denying the obvious. You even use stats that compare white mass shooters with black people at their homes, doing nothing (Breonna Taylor for example). And you claim that I'm "naive". Which is the adjetive white supremacist use with white women who disagree with them.
Maybe the problem is not that I haven't read Orwell, but that I've also read Octavia Butler or Ursula Le Guin. And that I see and listen.
So here is a message, we see you and we don't like what we see. We won't support you or "give you a chance" and we would taught our daughters, friends and sisters to also avoid men like you. From the rest of the world perspective, people like you are making US full of shame, not great. Now you can rage, but that won't change the truth.
