I remember a similar sob story from an acquaintance of mine, a white woman, who converted to Islam some years ago from a Protestant Christian background. She would complain about how her family treats her differently, they don't accept her new beliefs, they're distant to her, some of them are nervous having her around their children now, etc. Granted, all of this is absolutely explainable by the fact that she now wears the prescribed female Islamic dress at all times, and insists on having her own beliefs presented as on equal footing with those of her still-Christian family members. I told her that, rather than it being unfair that the rest of her family does not treat her like she's the same person she was before she converted, it is absolutely fair that they treat her differently now, since she is not the same person since she converted. Duh. Muslims are such babies. I converted to Orthodoxy around the same time that my father converted to his Filipino anti-Christian cult ("Iglesia Ni Cristo"; yuck)...you don't think that causes conflict? Conflict is part and parcel of having deeply-held beliefs that don't agree with whatever the majority believes.
I feel no sympathy for Catholic (or other) converts to Islam. They're deceived, confused fools, desperate for meaning that they cannot find in their bankrupt spiritualities, and hence latch on to simpler but also bankrupt Islamic ways. Given the population we're talking about, the saying patadas de ahogado (the kicks of a drowning man) comes to mind...
