I remember a time that even a teacher saying this to a student would be considered inappropriate activism about a controversial topic.

…Like right now?

From my perspective (millenial) raised in a conservative area, climate change discussion went from ‘kinda iffy in the past’ to approved to expected, then suddenly lurched to more taboo than I’ve ever seen.

I can’t even discuss it with my college-educated older relatives without them ranting about it. It’s a total taboo; they think I’m nuts for even bringing it up as an existential problem.

I can only imagine what parents would say if teachers said that now.
