I have personally witnessed a similar ranting incident on a subway, but the rantee was Chinese. The middle aged black lady, to judge by the content of her rant, had had a job cleaning for a Chinese family, and had not been impressed. Or to put it another way, the Chinese family had not been impressed by her work ethic, and had complained.

The Yahoo News version of this story has unmoderated comments going across the screen in real time, which is amusing.

It's another "Everyone thinks they're Rosa Parks" moment, but in this case it's white people failing to give up their seats on public transit for blacks that's racist.

Black woman goes on angry rant against Jewish man on subway, New York Post, May 28, 2018 A black woman went on a rant against an Orthodox Jewish man aboard a crowded city subway train after he called her racist, video of the incident shows. The nearly two-minute clip, posted last week by Twitter user @Chrisfrench_, begins in the middle of the heated morning confrontation between the pair on a Bronx-bound 4 train at 8:53 a.m. “You said I’m racist so you tell me what I’m being racist towards … because you’re Jewish and I said if a Jewish family got on here, somebody would have got up. That is not a racist statement. That is a factual statement,” the woman can be heard yelling at the man as they both stand on the moving train. Israeli national broadcaster Arutz Sheva identified the man as Yossi Wolfe, a 31-year-old Wall Street Journal software engineer. Wolfe told the TV station the hubbub began after another African American woman – with three small kids – boarded the crowded train last week and no one gave up their seat for them. “So this other lady started screaming at everyone around her, saying ‘Why are you guys not getting up? This lady’s here with her three kids,’ ” said Wolfe, who had been standing, “and then she finally said, ‘If it was a Jewish family y’all would have gotten up!’ At which point I said to her, ‘Can we please not make this a racist thing?’ ”[More ]

Of course, trying to remonstrate mildly with blacks violates what we call Derbyshire Rules, as expanded, memorably by Lawrence Auster. Some relevant ones from Auster:

10(m) If you see a black man with his baby daughter who is crying incessantly, do not walk up to him and ask him if the child is all right. Mind your own business. 10(o) If you see a black man drop a beer bottle or other trash outside your home, do not ask him, even very politely, to pick it up. 10(p) If you are walking along a street, and a car with black males in it almost runs you over, do not yell out, “Hey, watch where you’re going!” 10(s) If you find yourself in a subway car with a group of misbehaving blacks, do not ask them to relax or calm down. Do not say anything to them. Promptly leave the subway car. (July 31, 2012.) VFR’s Rules on How to Protect Yourself from Black Violence and White Political Correctness

The Twitter user who posted the video is black, as you can see by his avatar and the poll he posted.

You can also tell he's black because he thinks black. Two of his follow up comments to that Tweet above are:

Didn’t think this video would go as viral as it has. I myself have been called racist just for posting, which is weak, but no matter. I regret posting now, because everyone has run rampant with the “angry black woman” narrative, and it’s really disheartening.

I ask you all, is Anti-Semetism a real thing? Yes. Is being human a real thing? Yes. Is gentrification a real thing? Yes. Is prejudice a real thing? Yes. Let’s ask ourselves these tough questions before hitting send on a tweet. Be blessed y’all.

No one who is not black would think that it was wrong to watch that video and go with the “angry black woman” narrative.
