When someone tells me I've misread the intent or meaning behind something they've posted negatively and they correct me, I take that very seriously.
A long time ago, I wanna say like 9 years or so, I was in the middle of a mental health crisis. I didn't post about it, so nobody knew it was going on. But someone picked that exact moment to take something unrelated I posted out of context and read it in the worst possible faith to paint me as an asshole, and nothing I said seemed to get through to them that they were really heavily misreading me. Me fighting back at all was just taken as more proof that the horrible way they misconstrued my words was the correct reading.
It was awful. Being told I was a horrible person over a misunderstanding that the other person refused to let me defend, while I was already struggling with my mental health was one of the worst things I'd ever gone through. I cried and screamed and suffered in silence.
You never know what someone's going through on the other end of the screen. They could be going through some horrible shit that they just haven't themselves posted about. The last thing I want to do is pile on.
