The term "social justice" has been robbed of its original meaning in the same way as words like gay, rainbow, etc. Now the phrase is just a big red flag, and rightly so because of the way it has been agendized. (is that a word?) Social justice, even though I cringe just typing it out, has its right place when used in right teaching - the papal encyclicals Rerum Novarum and Quadragesimo Anno are probably the gold standards.
And although I would say Marxist rather than fascist, I agree with you regarding how it has been fashioned into something more important than the fight for unborn life. And abortion is the ultimate evil that will bring down a mighty judgment on us.
Hayek on “social justice”:
In substance this has meant that the individual is no longer bound only by rules which confine the scope of his private actions, but has become increasingly subject to the commands of authority... With the presumed moral superiority of a society whose members serve the same hierarchy of ends, [this has] made the totalitarian trend appear under a moral guise. It is indeed the concept of ‘social justice’ which has been the Trojan Horse through which totalitarian has entered.
