Of course, the collective is so abstract that we must have a committee to represent the collective, interpret the needs and desires of the collective and act in the collective's interests.
Who gets to be on this committee? The people who decided we needed the comittee in the first place.
And if you're not on the committee? Well too bad for you. Your interests may be found to run contrary to those of the collective.
At its core, "social justice" is another tired revolutionary propaganda slogan for that most timeless element of society: thugs and criminals who seek to steal what others have earned honestly.
