I'm specifically thinking of the CanadaPolitics subreddit which is solidly centre-left, where this happens consistently. Ditto the Ontario subreddit. General issues subs with centre-left politics that shift hard when a subject that was fixated on by an interest group popped up. Likewise, threads on covid policy were generally supportive of the scientific consensus... Until the subject of keeping gyms closed comes up, where the bro-science faithful would appear to declare all covid restrictions a crime against humanity. It's not astriturfing or anything malicious, just the natural result of a subject being a disproportionate interest to a highly motivated subset of the community.
