The confederate flag is not the flag of the US, why would he use that (ignoring all racial implications)?
Should people in Russia also have the flag of USSR? What about East Germans? Yugoslavia?
No, none of those are countries.
Entirely true. If "countries" not entirely recognized start getting flags, WarLight becomes a clusterfuck and it would spark quite a lot of political heat. It's better to just avoid it. The Confederacy is no exception.
The same is also true about Scotland, by the way, Ox.
The fuck, the confedary isn't a country... Not de facto nor de jure. Plus most people think that this flag is a racist symbol instead of any kind of poor cultural pride one.
This, however, was a horrible argument. Doesn't change the fact that is was not a racist symbol. Such a situation is effectively the same thing as suddenly spaniards banning the basque flag saying basques are nazi supremacists that want the destruction of the castilian language.
Just because most people agree on something doesn't make it right, you should know that considering you live in a place that gets screwed by none other than stupid mob mentality every twenty~thirty years or so.
