<p>I didn’t notice at first that this was an old topic, but since I read it all, I’ll post anyway.
I think it is reasonable and to be expected that parents would be disappointed and unhappy if a child wants to marry somebody of a different religion, especially if religion is important to the family. I personally would very much prefer my children to marry people who share the same faith (although not necessarily the same exact flavor of faith) as they do, because I actually believe in it and think it’s important. In discussing the pros and cons of any potential spouse with my kids, this would be an important issue to think about. If my child nevertheless decides to marry somebody of a different faith, I wouldn’t cut them out of my life, though. But I can’t pretend that it wouldn’t matter.</p>
