Excellent though long speech. Well worth it.
The speaker lays out that you should never use the term again unless you are a Marxist. Social justice means whatever the Marxist wants it to mean, but really it is state-run socialism. Tyranny with a pretty wrapper. Like most of their fields of study and nomenclature (CRT, gender studies, safe space, microaggression, trigger warning, institutional racism) the left simply makes up things without any sources and it becomes “academic”. No attribution is necessary, it is just one persons thoughts, and then it becomes “science”. Weasel words and garbage academics. He also destroys the narrative the Christians should be all-in on social justice, since those pushing it view Christians as part of the “oppressor” class.
