I think those points can help but based on my longterm experience so far I would focus on other areas because even if most discussions look technical, in fact, it's about the social part of the game:
The most important step is, tell your boss that you disagree! Don't tell your colleagues that you disagree with the decision and hope one of them will tell the boss. Tell it your boss directly, ideally one on one without a further audience.
Try to convince him but don't be emotional, use simple facts and if he disagrees, he disagrees. This is not the end of the world! It's his role to make the call, regardless of whether you like it or not and he will be responsible for the call. Remember, sometimes it could also be a test to see who can deal best with decisions he doesn't like.
And finally, concentrate on the next steps that needs to be done, you can't fix the past, you can only change the future. Even if you are not happy with the previous decision, try to make the best out of it. It will not be the last decision you'll face in your life, there are plenty to come and staying positive and focused will bring you in a much better position when the next disagreement pops up.
For further actions, you may consider blocking this person and/or reporting abuse
