This is good, but the fundamental problem is with Catholics thinking that remaining within a political party that supports abortion as a civil right and attempting to dismiss this fact by pointing to conservative support for things like specific wars (or war in general) or the death penalty neutralizes the scandal involved in belonging to such a group is a moral option.
When will Church leaders tell Catholics that it's as wrong to belong to organizations that support the culture of death, most notably through support for the legal option to kill preborn babies, as it is to belong to a Masonic lodge?
And when will so-called Catholic politicians who support legal abortion be told, without equivocation, by all bishops (including the Holy Father) that, by supporting the culture of death, these so-called Catholic politicians are not in union with Rome, may not receive Holy Communion, and will be excommunicated if they persist in supporting legal abortion?
