If the liberal politicians and other liberal Catholics in the Church don't like it they can go worship with the Anglicans.
I’m tired of it too. It’s either baby butchery or it isn’t. The Church has to teach, and allowing known public pro-baby butcherers to not only take part but to loudly proclaim that baby butchery is cool with the Church isn’t teaching. They have to be called out by name and told to repent publicly, changing their policies on baby butchery and admitting that baby butchery isn’t cool with the Church.
It’s true that they have already seperated themselves from the body of Christ by their actions, but this does not address the teaching aspect for other Catholics.
