You might not care about nationalism, but competing nationalisms care about you.
True to form, Minecraft creator and Swede, Markus Persson (a.k.a. Notch), took to Twitter later and applauded Swedish members of Reddit.com for vandalizing the Donald Trump fan-page for their opposition to Muslim immigration. Lacking any self-awareness, the Swedes hold pride in their lack of pride.
Coming from Persson however, this lack of awareness it not all surprising. He had previously prohibited Minecraft server admins for charging their clients for in-game perks, citing "exploitation". He would later sell his game, then maintained almost solely by his employees, for over $2 billion. Said loyal employees would receive nothing for their "exploitation", and Persson presumably still carries the title of socialist.
