You've identified the problem. It's never "reddit", it's a specific subreddit. It really depends on the size of the subreddit. Smaller subreddits can easily get riled up, and also create a sealed echo chamber by banning people left and right. But I wouldn't worry about a sub unless it was really big.

For example: I'd say HBO should worry about what the game of thrones related subs are saying about their latest show (which is good, shoutout) but only as a vibe check. The normies will always outnumber the kind of people who go to a subreddit to discuss their favourite show. Normal people just watch and forget.
