The United States is one of the few countries in the world where people born on its soil to alien parents are automatically granted US citizenship. However, citizens by birth are not necessarily “natural born”, as the phrase has been a subject of judicial debate.
Musk, like Trump, is a narcist who loves to see himself in the news. Like a toddler deprived of parental love, he, like Trump, will frequently “act out” by saying outrageous things on social media to get any kind of attention from people.
Musk only cares about leaving his mark on the world, to gain immortality. He would prefer to be loved for eternity, but if he can’t, then being hated for eternity is an acceptable second prize. This is why he started off talking big about taking humanity to Mars, but now spouts right-wing hate.
