Good person alert

A sarcastic insult often directed at performative social activists (sometimes even by other social activists), particularly those that are perceived as try-hards that use "moral purity" as social currency and/or emotional validation. Essentially dissing them in a way that says "congratulations, you got the attention you're clearly craving"

Persona A: Oh you shouldn't support or even talk about Harry Potter, the author is very transphobic

Persona B: 🚨 Good Person Alert🚨...Like I get what you're saying but this boycott has done jack shit so far!
