While all that's pretty vile, I'm pretty sure you can find plenty of similar vile comments from citizens of all Western countries on Elon Musk's twitter. You can spend about one minute guessing the replies to his tweet against racism and find plenty of examples.
Maybe there's something I'm missing?
ignoring as too hard participants from (mostly) non-english speaking countries, english speaking twitter includes participants from the us (330m), the uk (65m), canada (40m), australia (25m), ireland (6m) and nz (5m). 6/471 = 1.3%.
