Something my dad said a while back, which he says is from a video he watched where a guy went around and asked... he said, what has Trump done as President to make you hate him? What policies did he enact, or what orders did he sign?
I have the world's worst memory so I can't list any off the top of my head although I'm sure that question can be answered as is, despite it being a loaded question and a Ben Shapiro arguing technique.
You can say someone deserves to go to jail for their conduct before becoming President-- I'm talking things like Trump's own grooming and pedophilia yet to be discovered in a legally-holdable capacity (but due to his ties to Epstein, it's all but certain). You can absolutely say you hate a guy because he's vocally misogynistic, bigoted, a white supremacist, a fascist, a wannabe dictator... And you have every right to say he shouldn't be President, he shouldn't have any kind of money or power, he shouldn't have command over the military or nuclear systems, and/or he shouldn't be representing us on the international stage.
