Your manager should be doing this for you. Complain to them and start saying you are unavailable.

CC each rejected meeting to your management including the cost in scheduling overhead, loss of flow, and actual hours.

If your direct management is inept, go to senior.

There are ways to do this without coming across like an asshole. Unless you have a very good relationship with your boss, or you work in a toxic hellhole, you probably don't want to be forwarding meeting invites with passive aggressive cost analyses about your payroll cost and loss of flow which would probably take you have the length of the meeting to figure out anyway.

At the end of the day there's only so many hours, they cost, and resource allocation is a management decision. Taking emotional and personal interpretations is a chump's game. What's next, PC second-guess the interpretation of any point at every meeting and email? Not useful. How much time would that waste?

If you can't be direct, go somewhere more engineer-oriented or don't ask for help on HN.
