From what I can gather, this guys are hardcore Trotskyists so they disown Stalin as a "reactionary." Weirdly, they do seem to have some kind of soft spot for Putin though, even though he is running an oligarchy. I guess they just despise NATO more than they do capitalist, Mafia-run Russia for some reason.
Interestingly, they feel they are the only true left. All other groups, whether they be hardliners like Socialist Alliance or moderates like the Labour Party, Greens and trade unionists, are all the "pseudo-left" to these guys because they are either prepared to work within the system or have been distracted from economic issues by identity politics. Hence, only Trotskyists like themselves are the true inheritors of the mantle of being the Leftist opposition.
That's my take on them from the occassional glance at their website, anyway.
I've never been good at ideology, although I gladly admit to being a lefty of the anarchist side. When I was at uni I did some subversive stuff with friends of the Dutch CP, but I didn't quite share their religion. When it became clear to me that the Soviet Union wasn't much better under Brezhnev than under Stalin, even if less genocidal, that friendship soon wilted, although I remained a subscriber to De Waarheid well into the eighties. I see commie jargon hasn't changed much, although I miss jewels like the antagonistic struggle in the Western metropoles, so loved by our German comerades.
I well remember the ideologic sectarian strife in the left part of politics. There's a nice part in Python's Life of Brian that illustrates it nicely:
