Cannot post comment due to content

I received a "cannot post due to content" pop-up on a comment that contained no profanity, or personal or political references. I spent about a half-hour editing and re-trying, without success, so I sent it to the moderators.

I fully support your intention to filter out such comments. But the site needs to provide some explicit feedback, such as the sentence(s) that caused the objection, to teach commenters what is causing the objection.

Thanks.
