If you ban the swastika, then you also have to ban the hammer and sickle, no if's, ands or buts. Double standards much?
No, not really. The Hammer and Sickle was representative of a series of leaders and time periods in the 20th Century Soviet Union, many of which varied from Stalin. However the Swastika is associated (primarily, any fucking idiot who says it has a different meaning is wrong. I don't care what it meant before the Nationalist Socialists, it's a Nazi symbol.) directly with the one leader and regime - Adolf Hitler and Nazi Germany.
And to "boil it down" and suggest that Stalin killed more people than Hitler, I counter by saying that Hitler's actions caused more deaths than Stalin's. World War 2, a conflict which was driven by Hitler, resulted in 70 million casualties. 70 million. That's like if you executed literally everyone in the United Kingdom, and then the population of Scotland once again.
Hitler was, indisputably, more of a "bad guy" than Stalin, and his symbol represents that.
OT : Yes. It's one thing for the Nazi soldiers to be wearing them. They did wear Swastikas and had Swastika flags on their buildings. But the players who have them as their emblem are, bluntly, trolls. Or possibly Nazis, but far more likely to be people trying to be "edgy" and get a rise by using on of the single most recognisably terrible symbols in the world.
