BP Totty, thanks for the clarification, because otherwise I too would have feared what message you were giving your son.
The Hamodia articles were interesting, in context. Yes, there’s the (apocryphal?) story of the guy who hid his yarmulke on route to an interview, last minute decision, and did NOT get the job due to a perception that he wouldn’t stick to his principles.
OTOH, last year Rabbi Reisman spoke about nisyonos of the work place. Didn’t advocate ditching the yarmulke but evidently, the way he spoke it may still be an issue for some. But as time goes by, there are probably progressively fewer people for whom this is so.
