You're either a troll arguing in bad faith. In which case, I hope you find better things to do with your life. Or you can't see the logical fallacies in your own worldview, which is a sure sign of being brainwashed by your news sources. In that case, I hope you are able to see the truth one day.
You said both of these things. Please explain how they can both be true.
