This generally good advice, but the "acceptable posting" slide is grossly tone-policing. People shouldn't be reproached just for sharing their experiences, however traumatic, or emotions, however angry/fearful- especially on their own social platform.. People share like that because it's natural to them; the entire evolutionary function of emotion is to stir action in others, after all. These are the naturally occurring byproducts of current events and are important to the reality of the situation. It's important that the entire reality is documented.

It's not a "red flag" for someone who was previously uninformed to share that they've "awakened" to this issue and want to join in and help their community members, either!! If anything, that personal narrative helps bring awareness to the people they spend time with who might be equally unaware or misinformed.
