Sadly, some of these girls have no idea what they are wearing, or actually care if they do. Posting a Nazi symbol, of which the German Third Rich killed 30 million people, and very offensive to Jews, including myself and others, is not cool. They sadly have no clue of history, and just like to provoke people, whereas they would never wear any of that any public event, let alone anywhere outside without creating major chaos. Want to be proud of your heritage, sounds good. White Pride Symbols ... whatever - as long as they don't infringe on others. But Nazi symbols are fucked to wear - for many reasons.
Bu alas, I am not a PC person, but whereas you enjoy these girls wearing those symbols, for me, a snow bunny is a cute girl, whereas as competitor, and regardless of race, religion or where they are from - who looks awesome, and loves to be photographed where snow is around.
As for any pictures under 18 years old, don't even think of posting anything here, or they will be deleted. Report it asap - that is not cool.
