Not such a stretch when you realize that was not the reason he was objecting to it, else he would ask the mint to stop printing dollar bills because they have Washington's face on them.
He objected to the Nike shoe because along with the swastika and the confederate flag the 13 star Ross flag is also used as a white supremacy symbol, for that wonderful time 250 years ago when we all were white.
And while I, and you apparently, did not know the Ross flag was used that way, supremacists and black peope did and that's enough for me (he said, as he proudly laced up his Converse Chuck Taylors, now owned by Nike).
