I think that it can't really be reclaimed. there aren't many symbols in the world that have been co-opted by racist cunts but this is one of them and it cannot be reclaimed.
I for one would love it if the fascist left "reclaimed" the swastika !
How far back do you want WW2 to start? Japan was vying with China for a good 40 years before World War 2 happened, they were fighting before NSDAP even existed to take the swastika as their symbol. China vs Japan was a big war, but it wasn't really part of WW2 until Germany declared on the Soviets in 1941
Speciation Is Gradual
