I always wonder what sort of mental gymnastics this sort of person would perform if you showed them water parks, malls etc in the DPRK? If they maintain their flawed logic that 'water parks' == 'no concentration camp' then they have to admit that the DPRK is not the hellhole the western media makes it out to be.
It's not gymnastics, the asshole saying this knows it's a bullshit argument, but they like that Israel is killing brown people to protect their tasty colonialism treats so they put crap like this out there to run over. Most hardcore Zionists are cynical machiavellians.
