The objection I have with that is that it's reductive.
"It's not *so* bad" is different than "it's not *entirely* bad", and my objection stands, whether or not "someone else could achieve good results"
To hold a strong opinion on whether those terms apply, I'd need more information than is available to the public, and go on a case by case basis.
For example:
The IDF claims Hamas use civilians as human shields. Hamas denies it.
Hamas claims the IDF targets civilians. The IDF denies it.
And I, with no access to internal IDF communications, and no access to internal Hamas communications, don't know what to make of all the videos and articles supporting and debunking both claims.
If the goal is to determine whether Israel actually is guilty of genocide then that approach isn't useful.
The sensible position is to be conscious of what one doesn't know.
It's less satisfying than believing that one side is just evil, like the person to whom I originally replied: https://news.ycombinator.com/item?id=45766601
