So you are insisting that when the links you link speak of social justice they speak of the very recent movement that is rooted in the works of critical theory?

I doubt it.

(one of them compares a modern movement to the civil rights movement...)

I'm talking about the online sub-culture that has sprung up in the last 5 years. The ideas they promote are a distillation of various crit theory stuff, like safe spaces, trigger warnings, micro-aggressions, etc. They are the reason why the term "white privilege" is now virtually a household term even though it's been around since the 1980's. Not sure what your purpose is in arguing this very simple definition, but if you don't agree then have a good day I guess, not worth any more of my time.
