I do not wish to go into an unneccessarily long discussion about this, so I'll say this short. Nowadays the term "communism" is more of a collection of ideologies, rather than a fixed specimen. Of course, there's the more traditional examples (Stalinism, leninism.. etc) and there is the more adaptable kinds, mostly the so-called "new-age" variants that isn't too uncommon here in Sweden, which of course is a socialist country.
But you're right, the group is horribly inaccurate in it's appearance. The term communism, as I said before, isn't really what I believe in, but it's still the closest I can come to when using the more well-known terms. And the picture is from a Swedish youth-group called RKU, who practice Marxism-Leninism. My apologies for that.
Thank you for the input.
