I would argue that this title implicitly suggests there’s no genocide in Gaza while the other title doesn’t reach beyond the bounds of Gaza.
As to the “wiki is a bad source” I don’t claim to have any knowledge of that poster’s thoughts, but here’s a couple possibilities I’ve come up with:
They thought it was interesting that the genocide was evident to the “ordinary” person that edits wiki despite them thinking it’s typically a bad source
They are just some random ml user whose opinions on wikipedia don’t strictly match that of the concensus of lemmygrad, hexbear, et. al. Since those instances are more united on that stance than I’ve observed Lemmy.ml to be (right or wrong as they may be, not making a judgment here)
I gave their profile a cursory look, but I couldn’t find this in the few handfuls of posts I looked at. Do you have a link to a comment or two showing this, maybe I missed it?
