How do you say "There's no point of dragging a non-winnable argument with you, so if you want this feature to be approved this afternoon, I'll revert back my changes so that you can stop bitching on this issue already!"?
It's a job, have discussions, not arguments. Chances are whatever you're arguing about now won't matter in 6 months. And if it does come back in a bad way you have public records clearing you off.
> Getting in a pointless PR argument is one of the soul crushing reality developers face everyday.
Happened to me a few times in my previous company, moving to a new job with less man childs and power maniacs fixed everything. It's not an issue a PR issue, it's a people issue.
> I'll revert back my changes
Settling on specs before implementing things help with that, it makes arguing much easier when you haven't already built a solution.
