For me, both the NFL and NBA have been mostly black for all my life. The 1985 Bears were the last majority White team to win the Super Bowl. The 1989 draft was the last that could be described as White-friendly. Both of those happened before I was born. Maybe because I'm too young to have the feeling of betrayal by the NFL going from a relatively White-friendly league to one that's distinctly anti-white, I feel differently.
The NBA has always come across as glorifying blacks left, right, and center (especially left), while the NFL is at least dominated by White quarterbacks and gave us good storylines like the Brady vs. Manning rivalry. Now that it's embracing the BLM (bowel) movement and trying to cram black quarterbacks down our throats, I see it slowly sinking to NBA levels of anti-whiteness.
