"We" don't know that, in fact, you don't know that. You just decide to call that. It's of course not centralized in any way, thus not official. But I let that pass.

I guess you need to have a Ministry of Truth before you can say there is an official narrative. You could try traveling to Russia or Germany and publicly question a few things and see how that'll go. Although staying the US and publicly question things might also have ugly consequences. If you're large enough of a public figure.

Earlier, you stated that 'the official narrative' is that the UK and France intervened because they loved the Polish people so much.

No, I never said that they loved Poland. I stated that they did it to save Poland. Which was the official reason for it and is still repeated by many. But even if you scrap that you still have the official narrative of "Big Bad Hitler".

No one has been called a revisionist, let alone jailed, for pointing out that the Western powers acted out of Realpolitik and not empathy.

Of course not. That isn't revisionism. For revisionism you need to actually question the reasons behind that Realpolitik and the various events of WW2.

The "revisionist" - it really isn't plural - you follow is a fraud.

I don't follow a revisionist. I am a revisionist.

Any number of incorrect views are also not offered mainstream platforms. That in itself proves nothing.

WW2 history isn't just "any number of incorrect views". WW1 and WW2 are the most significant events of the last century and shape the world to this very day. It should be openly critically researched and debated. But it isn't.
