Celebrating the end of WW2 is racist because it happened against Japanese?
Since the day marks the surrender of the Japanese, it's somewhat racist.
This is nonsensical. We weren't fighting the Japanese because they were Japanese; we were fighting the Japanese because they bombed us. There were certainly some racist actions taken by the US during the war, but that hardly makes celebrating Victory Day racist.
It's also pro-nuclear weapons.
That's like arguing that the Fourth of July is "pro tar-and-feathering" or that Bastille Day is "pro-guillotine".
Unlike those two dates, nuclear weapons were actually the reason for Victory Day.
