Of course I read the whole story. Very often people who have BO are so used to it they don't notice. If there is some sort of systematic discrimination against Jewish folk, this (and a lot of other stuff) would have happened many times before. I'm sure the BO must have been pretty bad. But it does remind me of people who proselytise in countries where it's illegal, and then go on claiming it's religious discrimination.
In my first year of teaching, the principal had to send this one young man home a few times for the same reason. Eventually counseling helped him overcome his personal hygiene problem. Once we had a minority race kid being a real jerk in school. The dad came in, all angry that we were racially discriminating against his kid. Fortunately there were some scenes caught on video, and the dad relented. The kid was being a jerk.
I'm guessing this happens fairly often, but only made the news this time because he falsely accused the airline of discrimination. Most people would be totally embarrassed to have this in the news.
Body odor just one reason airlines might boot you from flight
