I agree. You shouldn’t be persecuted or harassed regardless of your religious beliefs, you should be equally protected regardless of if you are a Satanist, Wiccan, or whatever.
The actual wording of the law when translated from Swedish is closest to the English word “creed” I think, not “religious belief” as I wrote in my original comment, but I thought religious belief was a smidge clearer. I’m obviously not a native English speaker so I do my best.
And to further adress the “but what if I believe in My Little Pony would that count”, I mean… the spirit of the law does matter to the judges, you’d have to make a very strong case as to why you and your three friends should count as a protected “group” and why dismembering My Little Pony figurines is necessarily incitement against your group. I’m 99% sure no prosecutor would take you seriously. But I don’t know, I am not a legal practitioner. It’s up to the prosecutors to decide if a case seems to have merit, and then it’s up to the court to try what should and shouldn’t count as incitement under the law.
