These companies are so huge and such an integral part of society that they need to be made more accountable to the public, and forcing them to be more accountable to their workers is part of that. I think the recent proposal to require employee representation on the board of directors of $1B+ companies is a good start.
To be frank, I don't think you've actually conducted an empirical comparison of "black male + white female couplings IRL and in the media", nor do I think such a discrepancy would be worthy of comment even if it exists, and perhaps most importantly, I do not believe in the innocent motives of anyone who brings up the subject and then acts like they are only attempting to make an innocuous anthropological observation.
I'm not interested in a 'debate' about race-mixing with you. I just want to point out that when you tell on yourself like this, both online and IRL, people notice, and we'll treat you accordingly.
It's weird that he (and you) comment on that because if someone is extremely concerned about the media promoting miscegenation, that's usually a good proxy for them being a racist cretin.
I assure you that if you were to set up a booth in a shopping mall and start screaming slurs and lecturing about how gays and blacks and Jews are undermining the foundations of the superior white civilization, you would very quickly be removed from the mall.
