Betsy Ross shoe: Did Nike cave to PC culture?

Nike pulled a shoe featuring a historical version of the American flag from stores after former NFL quarterback Colin Kaepernick reportedly told the company it is an offensive symbol to some people. The 13-star "Betsy Ross" flag represents to many an era of slavery, Kaepernick, a Nike client, reportedly said. There are also reports the design has become a popular symbol used by white supremacist groups.
