"Why would I need to work at the same place to have any feelings towards how my wife is being treated though? Surprisingly we do talk to each other occasionaly;-) "

Sorry Dave, I guess I misundersood what you were asking. You first asked "how should I react" and I assumed that meant react to the security guard. Based upon your response to mine, it looks like you meant "how should I react to my wife's complaints about the way she is being treated".

BTW, Islam and Muslim religion aren't really interchangeable in usage. If the security guard is saying that the Muslim religion doesn't allow him to have contact with women in the workplace, that is just plain wrong. So, is the issue that this man appears to be a fundamentalist, who makes claims about the Muslim religion based upon his social conservatism and fundamentalist beliefs? Is this the beast we are talking about?
