“Defeating a culture of death” means promotion of a culture of the opposite. Which means evangelism. Crazy Evangelicals get this more and more. And a lot of churches, Roman Catholic and other denominations, need to find evangelism their own selves — as you point out some Christians can get so hung up on straining out the gnats of social justice issues that they will swallow the camels of abortion (and now also things like BLM murders). Asking the unchurched to be Catholics (or Baptists etc.) won’t do any good if the people of these institutions are not trying to get clean in the blood of Jesus.
Catholics are leaders in the pro-life movement. The problem we have is that our "leadership" is more concerned with Democrat Party politics than with stating the plane truth during election season--no Catholic may vote for a Democrat while the Party supports intrinsic evil. It's that simple... and that much of a travesty that they remain intransigent.
