without claiming expertise, isn't the same for all religions really? if you want to marry in a Catholic Church you and your couple will be required to convert to Catholicism (if they're not already).
if you want to marry in some sinagog (or whereever it is where the Jews get married), you'll have to convert to Judaism
why should we expect Islam to be different?
i think the real matter is that a lot of people assume all Muslims are totally driven by their religion. needless to say, that's far from being a reality. to that extent, one can easily cite the example of marat safin who is a Muslim and yet doesn't seem too compromised with a life of religious fervor.
This appears to be nonsense. If you want to get married in some cheaphell (or wherever it is where the Catholics get married) then probably, yes, one of the couple should preferably be Catholic, duh!
But there is no requirement for the other person to convert, or that the children should be brought up as Catholic, for that matter.
It's always been my understanding that the Catholic church allows a Catholic to marry a non-Catholic under the condition that the children are brought up Catholic. The non-Catholic parent is not forced to convert, though.
