A massive increase or whatever is still different from a massive Nazi movement, but eh, it doesn't matter too much.It all depends on what someone mean with massive though. Compared to how it was 10-15 years ago, it's indeed a massive increase in Nazi movement here in Sweden.
Clearly there's a movement going on inside the ranks of SD and there's no denying it. It's a safe space for Nazis today since they can always claim to be a part of a 'democratic' party while still expressing their shit. This really isnt a secret either, living in a part of the country where there's a huge SD following I know this first hand.
I don't like SD and I have no problems with calling them xenophobic and racist, but Nazi seems a bit too much and too premature. Then again I don't live in a part of the country with a huge SD following so maybe you know more how it is in practice.
