I'm seeing a trend that opinions must now involve name-calling, picking sides, and attacks on the reader's self-identity. Altman doesn't just share an opinion here, he calls those who disagree with him "gross" and suggest that there are only two types of people ("be the person... not the person...") I wish we lived in the kind of world where the Tweet said this: "I'm disappointed that so many root against Tesla. I support them because it's good for the climate and I believe in innovation. That's more important than making money on puts." Is it necessary to call people gross? Just read the other comments in this thread, there are plenty of rational reasons to short TSLA which don't make people gross.
