If you read the story, there's quite a lot of provocation on both sides, and it's not really clear who was at fault. This woman knew what the local custom was, because she had repeatedly been informed of it, but she deliberately violated it, apparently for a period of weeks.
Finally, she got into a fight with someone over it. Who started the fight, and who was most responsible for it turning physical, seems to me to be a matter of "he said, she said." I don't find this woman's account necessarily trustworthy. She seems to be the kind of person who does whatever she wants, and the hell with anyone else.
She admits to cursing and spitting at the man, although she accuses him of spitting at her first, which may or may not be true. She admits to kicking one of the men in his privates. Also, according to the story, many of the people on the bus thought that she was crazy, which may explain why a group of people tried to restrain her from hitting and kicking them.
Sorry, but I don't think this account justifies the kind of insults I see here toward anyone who wears traditional Jewish costume.
And you think a local custom that tells women where to sit on a public bus is OK?
