Propaganda is rarely reliable, from any side.
However, your conflation of the consensus view of the free world’s press with “propaganda” of the type explicitly pumped out by state-controlled Russian outlets is disingenuous to the extreme.
This is a common logical fallacy used by propagandists.
That's the problem with all these fallacies lists: things are a fallacy, except when they are not. So most often, they are just used as rhetoric weapons in verbal jousts.
No, fallacies are always fallacy, but a fallacy is an error in logic that does not imply that the conclusion is wrong [0], only that the argument offered fails to establish the truth of the conclusion it seeks to justify.
[0] An argument for the negation of a conclusion based solely on a fallacy in an argument offered for that conclusion is the definition of the fallacy fallacy.
I suspect not often.
My sources are not media and propaganda though. I read & also travel a lot. Before the war my cousin and I were importing carpet from Syria. During the war I traveled along Turkey - Syria border twice, also to the south side, Jordan.
And since the beginning of this war, I think about it almost every day, feel deeply sad about how a beautiful country got ruined by some dickheads for no reason...
