Even Six Flags?

The theme park gets its name from the six flags of sovereign nations that have flown over all or parts of the current boundaries of Texas (Spain, France, Mexico, Republic of Texas, Confederate States of America, and the United States of America).

Six Flags flew the Confederate Flag not the more recognizable Battle Flag.

The state even continued this theme in the design of its statehouse.

 To avoid any controversy the theme park has gone with an All American concept.
Believe me - there are plenty of angry Rednecks right about now.

I'd heard the story of the origins of the company name but I never really thought about it.

I was more familiar with Magic Mountain's more generic interpretation on the theme.
