"how dare the folks at Bridge and CUFC name their new joint venture 'South Carolina United'."

Consider the source, and trend...

When Newton Heath Lancashire & Yorkshire Railway FC changed their name to Manchester United (the bigg daddy United) in 1902, Manchester City already existed and had with that name since 1894.

See how well the naming convention united this City. Why would anyone expect anything better? At least Newton Heath only tried to unite a City and not half a State.
