It’s important to keep in mind that “common” doesn’t mean “right” or “positive”. Lots of things, such as CFCs in aerosol spray cans and radioactive elements in household items used to be common.

Do you remember what video it was? That’s a bit disappointing and I’d like to see for myself to gather context and tone. From all I’ve seen from Casey I’d expect gentle bashing of languages but not groups of people. Though I mostly have seen Casey on his own teaching or being interviewed one-on-one, I get the feeling he might be different in podcasts.
