> Everyone gets to share, there's no rules here about not sharing / having a different experience than others.

I disagree that this is a fair interpretation of the original objection. But assuming it is a possible interpretation, "that doesn't happen to me" isn't sharing an experience, it's sharing the lack of an experience.

Sure, yes, everyone does get to share, on a public forum, expecting otherwise is dumb. On that, 100% with you!

And yet, I feel like there's an important difference between sharing how your favorite color is blue, after someone said they like red the best, and sharing how you're not being mistreated, when someone is asking for help to stop someone from mistreating them.

You see how one is everyone sharing together, and the other appears to minimize the mistreatment of someone else?
