Gah, there are some flags in that list that really piss me off. For example, Fascist Australia. The Eureka Stockade flag (the Australian Fascist one) was used in a revolt that was literally "no taxation without representation". So that's about as accurate as making the original 13 Star American Flag the American Fascist one.
Okay, I will concede that the flag has been coopted by extremists in recent years (Communist as well as Fascist), but to many Australian Republicans it remains a flag to represent Republicanism. And you know, if this was a game that was set well past the Eurkea Rebellion, I probably would just grit and bear it. BUT THE EURKEA REBELLION WAS IN VICKY II'S FREAKING TIMEFRAME!
Read the wiki if you don't believe me. If there was a Republican Revolution in Australia back then, then that would be the flag that they would use.
Also New Zealand's Fascist flag is the flag of their
Rugby Team. There could be justification for it, I don't really know New Zealander history, but I really doubt that New Zealand would use a flag that could even possibly mistaken for Fascism.
