Progressive Politics

Because it would be more honest, within your definition, to call them DNC partisans.

I feel that doesn't quite capture the nuance of calling everyone they disagree with a Russian troll so they can ignore them (which is more evocative of MAGAs calling everyone to the left of Donald Trump a woke libtard agent).

What you wish to ascribe to them is not distinctive of MAGA

I'll admit I'm not exactly an expert on MAGA, but to me the distinctive features of MAGA is their hatred of dissent, intellectual dishonesty and lack of empathy for outsiders. Those are what I see as their main characteristics outside all the far-right nationalism stuff; they characterize the vessel in which you put the far-right nationalism to get MAGA.

so using MAGA to degrade them is not only inaccurate but dishonest because it specifically makes a comparison that is unfit, and ultimately only serves to degrade the meaning of MAGA by making it applicable to any run of the mill party hack.

Now I'm just now learning the term party hack, so would a person X described only as a Democrat party hack habitually call critics Russian agents and react to news of Israel committing more genocide against Palestinians with "we did it Patrick, we saved Palestine" or "leopards ate my face"?

Blue MAGA is naturally an opposite of red MAGA. Are democrats such nice people that their radicals are insignificant in comparison, or is it just a bad comparison?

The comparison emerged from exchanges in which DNC hacks/proto blue MAGAs were responding to legitimate criticism or predictions with accusations of the critic being a Russian troll/MAGA in disguise, so the nuance has always been more along the lines of "uh... you're acting awfully MAGA right now yourself", with the idea being that being not MAGA the DNC hack should be better than that. It's about the vessel of MAGA, not the contents.
