You're now being hostile which is quickly souring any chance of productive conversation. You're accusing me of saying things I've not said, you're blatantly ignoring anything that's inconvenient to your point of view, and You're making attacks/accusing me of "helping the enemy" because I disagree on how to deal with them. Not only are you not making any manner of argument on how you're NOT engaging in "No True Scotsman", you're becoming actively hostile at an ally because I only agree on 99% of the topic.
I've not once called them "far left" - I've called them the "farthest left (at least at a surface level) party with national exposure." That's not exactly a high bar. It also ignores the fact that there are genuine leftists that identify with the party. They operate WITHIN the leftist sphere, and they are grifters. You can't dismiss it out of hand and say that "well they are really leftists" - yeah, no shit, that's what grifters fucking do. Fucker Carlson doesn't believe in 1/10th of the shit he spouts off, but it doesn't make home not a far right grifter.
I'm not helping them, I'm trying to make sure that allies, both to my left and to my right (I wouldn't call myself "far left" but would call myself "leftist") keep some level of guard up against grifters that operate within our spaces.
My POV is: we are not immune to grifters in our spaces, you should maintain guard. Here's one example of a grifter within our space. (FTR, I could have also pointed to ML tankies that defend the actions of Russia and China in spite of the fact that neither are remotely Communist, socialist or leftist of any form). Your POV as it comes across SEEMS TO BE: Well, they're not REALLY far left (unclear if you only mean to exclude from "far" left or leftist in total), so no we don't have grifters on the left. If this is not your point of view, then far more time has been spent arguing about minutiae and leftist in-Fighting than explaining why you don't believe that grift is not a problem within this space.

And look, I really do not want to be hostile here, because I do Believe that we are largely allies (I don't know that we would agree on policies exactly as this is a narrow discussion, but we're so far from what either of us would likely want that it should prevent us from wanting to work together). I am however, not interested in engaging further if the discussion is just going to be hostile. I ain't got time for that shit.

Edit: Sorry, there is a point that you mentioned that I want to touch on: you mentioned that I am "just calling people what they want to be called" while you Believe in looking at their actions over their words... The thing is, we can only see that their actions are inconsistent with a leftist ideology because they have visibility and have been around long enough that we can now know that they are grifters. A decade+ ago, we did not have that information, so as far as most people could know, they were "leftist". I'm not including them to exist their actions, I'm using them as an example of our space but being immune to the grift. They may not be "true leftists", but they ARE "left-wing grifters." Because it's not about who they are, it's about who they target. There are farther-left grifters (likely including some who are state actors of foreign governments), but it's not as easy to identify who is and is not a grifter because we don't have as much info on them.
