Sometimes it can be useful to be aware of what kind of angle or narrative is being pushed, if it reveals any strategically useful information.

And then other times it's just a waste of time because they're resorting to spewing any kind of bullshit no matter how little sense it makes. More often it seems to end up being the latter, as part of the "grand" strategy of leftists not bothering to ever commit to any kind of serious debate or argument beyond propagandized points.
