Why is it that so far I haven't heard any white American on TV use the term "My people.." but I had seen a few African Americans on TV use it?

Unfortunately, I think it’s because for hundreds of years the word “we” when talking about people meant whites, it was an assumption, so now people distinguish themselves by saying “my people”. It could also be racial pride. Then again, I could be way off.

The American Dad cartoon intro the Father claims that he is from the “American Race”.

My people in what context?

There’s usually no motivation for the historically dominant social group to distinguish itself through public expressions of solidarity and shared heritage. Doing so is kind of obnoxious and could be viewed as a racist dog-whistle. It’s why “white pride” is bad, and “black pride” is okay.

I could imagine some sociopath oligarch saying “my people” while making a toast at the Bohemian Grove or speech at the Bilderberg Conference.

I can see validity in a trade union leader who happens to be white saying “my people” to identify with working class people of any colour.

I understand now. I agree with @Kropotkin.

I would add that I think white people (in the US) historically have been diverse and so they grouped themselves by nationality I think more than being white in some parts of the country. I grew up in the northeast and I don’t think most people thought in terms of white and Black like in Southern states, because we white people were Italian, Jewish, Greek, Irish, German, Russian, we didn’t think in terms of white being one group. When I lived in the South it was strange to me how white people never talked about their heritage before America, they focused on being Southern.

Society categorizes all Black people into one group, America practically stripped Black people of their diversity, and when they say “we” it has a lot to do with how society views them. Same with Asians, Latin Americans, etc. In their own countries the Chinese wouldn’t group themselves with the Japanese. In Mexico they don’t group themselves with Argentinians.

Because it’s TV and it is not a reflection of reality.

“My people” or “Our people” indicates that you are setting yourself aside from everyone else in the country you are in (unless you are using “our people” to describe all people in that country). Setting up that divide makes it possible to say you are better than everyone else or that all people of your particular divide are victims. No other reason to say it.

In-power groups do not have to announce themselves. When they say “everybody” or “normal people” or somesuch, they refer to themselves.

Let’s say you have a brother or sister, and you guys are being harassed and bullied by a large majority.

Your sibling and you are the “my people” that have to figure out a way to deal with the others giving you strife.

It’s your sibling and you against the others because the majority has issues controlling their aggressive behavior towards you for simply existing.
