That’s an absolutely valid point — it’s important to prevent discussions from devolving into chaotic political battles. But there is a clear limit to how far you can go. When moderation starts suppressing or de-emphasizing information simply because it doesn’t align with a certain viewpoint — even when that information is objectively true — it’s no longer moderation, it’s censorship.
What’s happening around Wikipedia shows how quickly the protection of truth can turn into political pressure: when a platform is accused of "propaganda" simply because its content is inconvenient for certain groups.
I really hope we are not yet at the point where mere disagreement automatically makes someone a propagandist who must be silenced by force.
