Among many issues: * contrary to the narrator's statement, the two males are not dressed similarly * they speak differently * there is no black female control

And of course, being a TV show, there is no systematic statistical analysis.

Now, TBH even with more rigorous protocol I suspect the conclusions drawn would be similar, but as it stands, this "experiment" is not altogether useful.

That was disturbing watch, but not necessarily because of the racist aspect.

I felt 70% of the reason why the Hispanic guy was confronted by people was because he was a much smaller than the white guy.

Had it been similarly sized black guy, nobody would've dared scolding him.

It's socially unacceptable to be racist, but we think being 'sizist' is ok.

Uh, are you really saying that big black people are not victims of racist abuse?

It sounds like he's saying "people are more likely to intervene if they think they could take the other person in a fight". If you're afraid because of a size differential, you're more likely to stay silent (not "you" specifically, but the societal "you")
