Is what i'm doing morally wrong?

Nothing immoral about it.. So what if your interested in Swastika Symbols, the Nazis Even Hitler... As long as your not thinking doing something immoral like following in the footsteps of Hitler and dream to be the Next Dictator of Germany or any other country and planning to plunge the whole world into another world war (Which I don't believe your going to do cause you did say you don't support them) then every things fine.. :)
