Obviously this is intentionally provocative, I get that claim. But I don't think you can quite fairly complain that it's pitting two oppressed groups against each other. They were already pitted against each other by the fact that one group regularly discriminates against the other. What do you think life is like for a homosexual who grows up in an Arab community in Sweden? Do you think they're allowed to express themself? Of course, from the little I've heard of the far-right in Sweden, there are some other reasons to just be displeased with the people doing this, but I don't know if the march itself is an entirely bad idea. It needs to be made clear to more insular groups of society that they can't get away with engaging in their own discrimination.
