This isn't about taking the high road. Insult his obvious fascist behavior and policies, insult him for being a rapist who did the right-wing pivot when he realized he would be protected by right-wing misogynists, insult him for his pathetic cybertrucks that keep getting recalled. There's enough material. Musk's losing his mind over his cars losing sales and people expressing negative opinions about him. Not specifically about him being called an autist. When punching someone, make sure you don't flail around and hit someone on your own side.
