I guess? You could instead link the post, that doesn't ping anyone and offers contextual information to other commenters since it was directly asked. If OP wanted to keep it private so that no one would know, they probably wouldn't have posted it on the public internet.
But it's kind of quaint/endearing that you wanted to protect their "privacy," though. Not a bad attitude at all, it's just not common practice since people don't tend to accidentally make posts about things they want to keep secret.
"I want to know how much I have to work" gives off vibes that you generally put in the minimum effort and want to know if you will actually have to try tomorrow.
This appears not to be correct, but that's just how people see that particular phrase. It offended her that your question appeared to imply that the level of workload affects your willingness to work in that unit. To mitigate what she perceived as your reluctance to do hard work, she called your manager to make sure that she didn't have to work with you.
Consider the reason behind your question. Would an accurate answer have actually affected your day? Most people don't have the luxury of knowing what tomorrow will look like. I understand the desire to be prepared and to know what will be thrown at you beforehand, since I'm neurodivergent too, but often these questions are for our own comfort and an answer is not actually necessary.
