The social justice crowd within the Catholic Church is doing that all by itself. Trying to blame others is absurd.
The term “social justice” started with the Catholic Church many years ago. AFAIK, it means we have a moral obligation to help other people.
The left took the term and twisted it to mean the government should forcibly take from people to give to others. AFAIK, that’s not the Catholic meaning, but some Catholics themselves might be confused about the meaning.
