Is it recency bias on my part to say it feels like this tactic is showing up in more places than it deserves to? The last American election cycle was terrifying to watch for precisely what you just described happening all across Twitter and elsewhere on social media.
Assent with {group_A} or be labelled complicit with {group_B} by default with little headroom for nuance or context.
No, but it is recency bias to think that it showing up in more places than it deserves to is novel. It has been an exceedingly common tactic everywhere for probably as long as civilization, or maybe language, has existed; it manifests in moral/religious/philosophical dualism, for instance, which is extremely widespread and ancient.
I’m not looking forward to the next election.
Then the villainization of anyone who disagreed with the activists approach as women-haters who think it’s okay to harass women only increased backlash.
