Yeah, though I'm not sure why it needed to be a theme now, especially when that topic had been dealt with to death in prior games (Gray Fox being interred at a POW camp in Vietnam due to his half-white status in MG2, the reference to J. Edgar Hoover in MGS, Raiden's nickname being "White Devil" (a Chinese slur towards caucasians in the region) in MGS2, the reference to Sigint being denied entry to various jobs before Zero got involved due to his skin color in MGS3, and Kazuhira Miller's childhood of him being mocked for his western appearance in MPW. And that's the canon games, non-canonically, there was Ghost Babel and the references to racism against the Boias and Eguabon's second in command being a victim of racism even from her own father). Then again, this game reused the theme of revenge that was used in Metal Gear Rising.

It has never been dealt with, let alone "dealt with to death" in the MGS Series. All of those examples are off-handed references and none of them tackle the real issues around the theme.
