OSTRACISM
It seems counterintuitive, but the greatest weapon we have in the fight against the Maga cult is ostracism. You should not have any contacts at all with any Trump fanatics. Friends, family members, anyone. If one or both of your parents is a nut, cut your ties immediately (if you haven't already done so). Don't take their calls. Don't respond to their messages. Act like they don't exist. You don't even have to tell them why they are being shunned. There's no reason to have any arguments. This just serves them; gives them another excuse to get angry. They know exactly what is going on. They support rape and murder and the destruction of America. You don't. End of story.
Isolation is a huge price to pay. There is nothing worse than losing a loved one. That is what they have done through their blind obedience to the cult: they lost you. Don't take this lying down. Make them pay. Make them suffer. Then, like a convict staring at a wall in a cell year after year, they will begin to understand what they have done.
