I have the sense that if an authority, be it a person or otherwise (e.g. a parent or some religious text), is extremely strict on some issues, they might come to be seen as unreasonable generally. This would have the effect of undermining their influence on all issues, even those for which most people would find their guidance quite prudent.
Is there a word or expression for this situation? It feels similar to "crying wolf." Does that cover it, or is there something more specific?
Edit: forgot an example sentence: I don't have a particular part of speech in mind, so I'll give a few versions.
"Adam had developed a reputation as being obsessed with the rules. As a result, he had become adjective, and people tended to disregard his disapproval."
"Adam had developed a reputation as being obsessed with the rules. As a result verb, and people tended to disregard his disapproval."
"Adam had developed a reputation as being obsessed with the rules. As a result, people tended to disregard his disapproval. A classic example of noun/phrase/verb."
Edit 2: A lot of useful suggestions in the comments that could be applied in situations involving what I'm describing, but none of them seem to be a general term/phrase. I suspect there isn't one. What should I do then - just leave the question unanswered?
