It's funny you mention this as my mother told me she heard about this a while ago as well and how prostesters have trying to say its ironic considering the people on the plane's connections to abortion clinics. We live in
Butte and have both been to Holy Cross many, many times over the years. While there is a small "babytown" sort of section for small children, and I believe there is even a large monument stone with a
Bible passage on it for the section (some psalm or something - I think it has a lamb and shephard on it) - as a memorial for dead children in general, I am almost positive that it makes no mention of abortions specifically. I think the memorial is more aimed towards infants that were miscarried, stillborn, died shortly after birth, and other sorts of things like that - aimed maybe towards children that didn't get the chance to be baptized. Holy Cross is a Catholic cemetery and I just cannot imagine that a memorial to abortion victims specifically would sit well, but I could be wrong.
I can't say for sure, as I haven't been to the cemetery since hearing this ot check things, but I think this might be a case of things being take slightly out of context.
In the meantime, I'd be really interested in hearing what anyone else has to say, as I'm really curious about this as well.
