Excellent idea. My brother asked a lawyer friend if he noticed how Africans were in every ad on TV in a portrayal of supremacy, when they are only 13% of the population. Carl responded, he hadn’t really noticed as he scratched his head thinking, you know, he’s right.
Your lawyer friend probably didn’t notice because he probably doesn’t spend much time in front of TV - and many whites that watch TV use options that remove much of the advertising.
At this point Hollywood movies are just 2-hour extensions of the same nonsense - problems caused by white guys being resolved by intelligent blacks and compassionate perverts.
There was a study done (albeit decades ago) the whites really don’t see race in ads. Blacks ARE more likely to buy if they see a black person in the ad. So why wouldn’t you fill your commercials with black faces. Not blackface mind you...
