Where are the men?
Men would get up and step in. There are no men in that train.
Of course there are no men. Society has emasculated them and turned them into game playing, pencil pushing geeks who think the world should obey their thought commands.
Did you not read about that couple in Baltimore, who were leaving their home, the GF is pregnant, and they are held up by some thug. The BF runs away and leaves his GF to be assaulted by the thug. That’s where the men are.
There are no white men on the train and the woman and baby are white. The attacker is black. Hence, none of the men in the train came to the help of the white woman and her baby.
Demography is destiny.
