That's not an explanation. I don't think it's too much of an exaggeration to say everyone supports "human rights and freedoms," they just disagree on what those are.
Except they are clearly taking a stance in opposition to Swedes' freedom to decide how they want their country to be governed.
You've never heard statements such as "I disapprove of what you say, but I will defend to the death your right to say it."?
That is, you don't draw a real distinction between repeatedly, loudly, and publicly calling someone a cotton-headed slop-spouting pig to whom no one should pay any mind and actively working to ensure that said pig is prohibited from spouting its slop?
