I'm always wary of people bringing up the paradox of tolerance; most of the time, it's just used as an excuse to justify censorship while claiming to be opposed to it. "When you censor me, you're being intolerant and that's wrong; when I censor you, I'm doing it in the name of tolerance, so I'm correct".

I'm not Swedish, so it's possible there's something that I am missing. But skimming the wikipedia page for the party (https://en.wikipedia.org/wiki/%C3%96rebro_Party#), I don't see anything that says the party is pro censorship.
