If they follow the logic that if you identify as "x", and they equate you with something else that is much more different, then it is wrong.
If you smoke cigarettes, you don't equate them to a pothead. If you are a conservative, I don't say you are a neo-conservative.
Socialism like Capitalism or any other economic model can function in hundreds of different ways. Stalinism, Leninism, Trotskyism, Maoism, Marxism, etc. are only a few of the ways Socialism can work. Socialism can be large scale or small scale. It can be with in a democratic system such as Democratic Socialists. It can be agrarian or industrial. Really there's no specific kind of Socialist so it's wrong to assume that if someone says they're socialist that they want a Revolution and to install a new Stalinist Dictator.
If someone says they are socialist, then they aren't really giving you all that much information about themselves. Only the ignorant are unaware there are many different schools/factions of socialism. The Bolsheviks are not the only school of socialism, they weren't even the only socialist group that took part in the Russian revolution during the early 20th century.
