Having a Supreme Court that is 2/3 Catholic hasn't done anything to change Roe v. Wade. The court is the court. Maybe it doesn't matter who appoints SCUSA justices.
Unfortunately, some people who identify themselves as Catholic are the furthest thing from it.
Scalia and Kennedy are the ones who most conservative CAtholics would describe as most Catholic. So, if there ever were a time, it would probably be now.
Scalia, Alito and Thomas. Not Kennedy (he swings either way) and not Roberts, both are CINOs: Catholic in name only
