It was combative because the OC called the recipient unworthy and you replied that it was because they didn’t understand things that most people who can read at a third grade level do.

That’s messed up, and I was intending to point out that that’s the implication of your comment so you could rephrase it if it was unintended.

Some people don’t seek to understand, but this person’s asking multiple questions to figure out what this means, and then wants to talk verbally because they’re not getting it via text. I don’t see a reason to suspect they’re not looking to understand.
