Now I wanna preface this with: People should absolutely be held accountable, especially up to and including people who hold power, and that goes for small cases where people wield power over a community
Now, holding people accountable is important, but more often that not, 'calling someone out' or writing up a callout post or whatever, these tactics are frequently used as a measure to silence and isolate someone. And maybe you've perceived that there are people who deserve this. You may have also noticed that proof, in a lot of context, is always easy-to-manipulate or fabricate screenshots and copy/pastes
But I think the most important thing to consider, at least when your 'callout' is directed at a marginalized person who already is at a huge disadvantage in society is: Would you be comfortable if your actions lead to that person's death?
Because in the case of marginalized people, this is what happens. Kiwifarms uses this as their main tactic, except in a twisted kinda psychopathic form, and it _has_ lead to the deaths of both cis and trans women.
Ask yourself if what you're doing is important enough to warrant someone's death.
