The concern is understandable, I suppose. It's just a convenient way to see clips from both sides of the conflict, and it's the best source for combat footage clips anywhere. I do have a working brain and can use it to identify when people have a polemic. I prefer it to telegram, which is the alternative. The comments are indeed... uh, very strident in their support for either side. So I'm not sure if it's "propaganda" so much as people regurgitating propaganda at each other at full volume.
Anyway, it's a war. Propaganda is essentially impossible to avoid without ignoring the topic entirely. Still, it's what we have to work with. And to be clear my sympathies lie with the ukrainian people.
