This, many times this. If you encounter pushback from everywhere – leave, don’t spend your life energy fighting bullshit.

I won't add much, but if this happens you must leave. Raise the risk. Document it. Document your recommendation and their decision, even if not replying or not making a decision was their decision. Tie it up with a bow on it, keep a copy, and leave.
