Let's rephrase the question.
How would you feel if your wife got fired because her boss's daughter saw you kissing some lady in public? That this would be discrimination and illegal is irrelevant; it's the Catholic church we're talking about. They're in the business of inventing excuses to control people's behaviour.
I'm with you on not wanting to be in the closet or hide who I really am... but I also understand that Life doesn't always allow us to express ourselves the way we want to.
Also, what makes your personal choices trump hers? You're talking about your comfort level. She's talking about her job. IMHO, making a living trumps "what I wanted out of poly."
