Sassem Bootboys was a skinhead/oi/punk band from Sassenheim.
They started around 2009 and split up in 2014. True: Their political affiliation was no doubt on the right of the political spectrum. But it was social right. They didn't want anything to do with extreme right politics. Even though it is mentioned lots of times on the internet; all these aqusations have been written by leftwing activists. At that period they were just as "far" right as Geert Wilders and Thierry Baudet are in present days.
Sassem Bootboys weren't on the far right and they never wanted to be assocated with nazi's, extreme right or like anything else. They wanted to stay as far as possible from these idiots. They even stopped playing when there were idiots in the audience who raised their right arm. It's a fact they only continued playing after removing these persons from the audience.

If you read their lyrics you'll know that they rejected these extreme political thoughts.
