Tangential (and not to attack you specifically), but I don’t understand the basis by which tech, HN included, judges itself to be more liberal and less reactionary than other industries. There’s just as many racists in tech as the rest of American society, with a special bend towards libertarian/scientific realism/racism that is much more pronounced than in other segments of America than I’ve seen. It’s traditionally been one of the most unwelcoming places for minorities (Hi Coinbase!), and has pioneered new workplace and have championed euphemisms like “culture fit” to exclude people who don’t look like them (not limited to black people).
