and this is relevant to the topic for the reason that (IMO) it makes a great deal of difference whether we consider that:

- people didn't post a trigger warning because they didn't know about that.

vs

- people didn't post a trigger warning because they are *intentionally* trying to elicit a negative reaction from others.

if we give them the benefit of the doubt and point out (gently) that we are triggered in such a way that we are taking ownership of our response then that is much nicer than

not giving them the benefit of the doubt, judging them to be pathological, assuming they intend to trigger us and as a consequence of that... feeling upset.

it is a choice yeah.

but i think it is nicer to give people the benefit of the doubt.

just like i'm sure you would prefer other people to give you the benefit of the doubt rather than judge you.
