Hey guess what? You’re the incredibly racist one. Because Chief Osceola wasn’t “full blooded Seminole” because first of all because there wasn’t such a tribe as it was a mix of numerous Native tribes, some French and Spanish oppressed whites and runaway black slaves. And second, Chief Osceola’s father was 100% full blooded white and his mother was at least partially white as well as partially black making him more white than Native American.
Osceola was born Billy Powell Jr in honor of his father William Powell an English and Scottish trader. His mother was Polly Copinger who was half white and roughly a quarter Muscogee Creek “Indian” and less than a quarter black. Osceola’s maternal great grandfather was James McQueen a Scotsman of lesser nobility who married a Creek woman whose name is lost to history. Their “halfbreed” daughter Ann McQueen (Osceola’s maternal grandmother) married a man named simply Copinger which is an Irish surname. But he is known to have been a descendant of an escaped slave who mixed in with the Irish and was approximately a quarter black to go with his white ancestry. So Osceola was approximately 5/8ths white (possibly more), 1/4th Creek and 1/8th black (or less). So there is absolutely nothing wrong with a white student wearing warpaint in traditional dress representing Osceola as he was a mostly white guy who was only a quarter Native American. Frankly, I can speak knowledgeably on the subject as my maternal great grandmother was 100% Cherokee and thus I’m almost the same admixture as Osceola (no black in my background or Irish, just mainly Scots, English and Norman French/Danish with a distant Jewish many greats grandmother who escaped the fall of Jerusalem and married a Knight Hospitaler ancestor when they lived in Malta before returning to England, but we’re close enough.)
And it’s not like Osceola/Billy Powell Jr. was the only mostly white leader of the Seminoles. His uncle Peter McQueen led Muscogee Creeks in the Creek War in Alabama and then led the survivors down to Florida where the Muscogee Creeks mixed with Miccosukee Tribe also moved down from Alabama and the descendants of several lingering native Florida tribes as well as French, Spanish and Black “outlaws” to form the Seminole tribe.
So learn some history before you go off on your stupid poutrage about how “offensive” something is to people you know Jack %+^+ about. And before you go who cares about the Seminoles…the three wars against them were the largest wars of Nativ American genocide and the second one involved full use of a standing army of 30,000 American troops (3x the number of American troops and 1.5x the total allied troops at Yorktown and more than any Revolutionary War or War of 1812 battle. There wouldn’t be a bigger American army assembled than the one that fought the Seminoles in the Second Florida War until the Battle of Bull Run in the Civil War).
So yes, there is nothing wrong with full blooded whites, full blooded blacks, full blooded Native Americans or any mixture thereof “cosplaying” as Seminoles because that’s exactly who the Seminoles were and who they remain today.
