Did the indigeonous people invent football so Mr. Kaepernick could have a career in the US?

No, white people did that.

White people have also been in America 500 years and built everything the modern world now enjoys.

Mr. Kaepernick is probably too young to know that.

White Americans were also the people who ended slavery in the west.

What an ingrate.

BTW, those indigeonous savages were slaughtering each other in tribal wars for centuries before white people came to America.

He probably is ignorant of that also.
