Oh boy where to begin.
There are a few reasons why MLs make up a considerable portion of "real world" Marxists.
First of all, the hegemony of the Third International/Kominform and the CPs even after the demise of the aforementioned organs of global counter-revolution. But why did this hegemony exist? Throughout the XXth century the CPSU and the Soviet Union were considered the bulwark of socialism. Communists were sent to the USSR to "study" Marxism; soviet manuals were printed by CPs and widely distributed. Most militants only had access to Marx and Leniin via Stalin/Kuusinen. Marxism-Leninism became the communist common sense.
Of course the oppositions weren't completely unheard of. How did the CP bureaucrats solve this? They persecuted Trotskyists (or anyone who disagreed with the official line, for that matter) through a relentless campaign of lies to discredit the oppositionists as anti-communists and fascist sympathizers; when this wasn't enough, well, they killed them (eg, Soviet Union, Spain, Greece, China, Italy, Czechoslovakia etc).
We should keep in mind that Marxism-Leninism is a state doctrine, an ideological justification of the reality of the USSR born out of the failure of world revolution. Socialism in one Country, for example, one of the cores of stalinism, had always been upheld by the right of the worker's movement (oftentimes by non and plain anti-marxists).
Another important point: stalinism is eclectic, opportunistic and pragmatic. Following a dialectical mystic parlance, Communists alternated between full adherence to bourgeois factions and mindless adventurism. That's how we can have DPRK and Nicaragua, Albania and China, Cuba and Vietnam and Yugoslavia - all of them under the banner of the "science of marxism-leninism" at one time or another despite their huge differences and contradictory interests.
Moreover, stalinists are nationalists. That's how they can appeal to the lowest common denominator of bourgeois ideology amongst the proletariat; that's how they perpetuate and spread it. That's how they can accuse trotskyists of being traitors (for all the wrong causes: embryos of class independence, internationalism etc). That's how they can support the progressive national bourgeoisie against "imperialism". Do you know where this ends? The rational administration of the bourgeois state and national economy. No wonder why many stalinists ended as eurocommunists, social-democrats or unabashed neoliberals. Capital has different needs according to its immanent contradictions, and if you're going to manage it, you'll be subjected to them.
And I call all of them stalinists. Even Kruschev. Even though they discarded Stalin and the cult of personality, the marxist-leninist Weltanschauung remained. It is not enough that one should criticize this or that figure, this or that crime, but the whole ideological universe they were immersed in. This critique would lead to the criticism of what constituted soviet society: capital.
Being a justification of the domination of capital under the red banner, stalinism led to the abandonment of the critique of political economy. Marx's magnum opus was suddenly a manual of political economy, not a critique of it. We should remember that Marx's categories are Daseinformen, forms of being fully developed in (specific to) capitalist society. Capital is a critique of the whole of the bourgeois world.
The most degenerate stalinists are at least honest. Here I take two: Bill Bland and Domenico Losurdo. The former argues that socialist society is mediated by the market; the latter, that the end of market and the state are utopias alien to marxism (!).

"We have seen: a social revolution possesses a total point of view because – even if it is confined to only one factory district – it represents a protest by man against a dehumanized life" - Marx
"But to push ahead to the victory of socialism we need a strong, activist, educated proletariat, and masses whose power lies in intellectual culture as well as numbers." - Luxemburg
