Yes Malena is hating on our country (and not because she criticizes SD per se)... no, it will be difficult to find open SD-supporters in the left-field PC-maniac that is the Swedish show-business, but these people are a very small proportion of the entire population though and it's not really fair to use artists as some sort of representation of the whole population.
The majority of Swedes agree with SD's stances on limiting immigration, and if you checked the polls lately they are equally big as S and M, so I think your idea that "no one agrees with them" is not very valid.
Yuck I hate that bad
... and yes this is a rare moment where I agree with you and them posing with that crap is shameful...
