OOOOOPs.
Sorry, didn't mean to start a debate.
Again, I apologize.
No, please don't; you have nothing to apologize for! Look, if you aren't a Catholic because you misunderstand what we believe, ought you not to come to a correct understanding of it? That way, if you still disagree, at least you're disagreeing with Catholicism, not a mistaken idea of what Catholicism is and what it teaches. And, if you don't really disagree ... ??
The reason I posted was that your objections don't make sense to me -- not that I disagree with you theologically, but that you seem to me to be objecting, not to the Immaculate Conception, but to something that the IC isn't. I'm trying to get at what that "something" is. If it's a real objection, trust me: I'll tell you. ;-)
