> The mental contortions required to conclude that "committed suicide" trivializes something, but "died by suicide" doesn't, are so extreme that I cannot believe anyone honestly holds that opinion.
I think the notion is that "committed suicide" is like "committed a crime" and harkens back to the Christian notion that suicide is a crime (against God). And so it's moralizing language that blames the person for killing themselves.
You can verify that this is a common notion among people who work in the field by Googling. For example, the first hit when I search for "why shouldn't we say committed suicide" is https://www.irmi.com/articles/expert-commentary/language-mat... which says:
> For example, the phrase "committed suicide" is frowned on because it harks back to an era when suicide was considered a sin or a crime. Think about the times when we use the word "commit": "commit adultery" or "commit murder."
> That leaves as the most likely conclusion that this document is not an honest effort to eliminate 'harm', but a mine-field, a list of sins and prohibitions, to be used as ammo against opponents.
It's interesting that you arrived at this conclusion before doing a minimal amount of research!
