Captaincy has to do with leadership, not nationality.
Your argument would have been clearer if you'd just stayed in that lane. But then you went to winger, being a "bad choice", and Gabriel lacking "English" being a hindrance. David Beckham was captain of England for a while, then Rooney, now Harry Kane. No one's ever had an issue with their on field positions.
No one is calling you a racist. Not yet anyway.
But, you're full of shit. As per usual.
