"When we first started talking about doing this, we didn’t really have an agenda, or any developed sense of why we wanted to do it. It just seemed like an interesting challenge; one that would force us to see things differently."
Perhaps the Social Justice discussed on Wikipedia is different from a social justice class. After all they say they're social justice teachers.
For instance this (http://www.gonzaga.edu/Academics/Diversity/Academics/Social-...) description of a social justice class sounds a lot more about raising awareness of social issues than a "LITERALLY beyond-communist ideology". Another example -> http://www.fatimahs.org/pdf/Teacher%20Syllabi/Sister%20Lisa/... So it would seem unclear what exactly they mean. I'd imagine that term is quite overloaded.
"The reason that $1-per-day eating is tied up with this is that social justice folks want to redistribute ALL resources, across the entire planet."
Perhaps actually reading what they have to say, beyond the line where they mention social justice and the 3 line description of what that means in Wikipedia, before jumping to conclusions, losing your head, and seeing "LITERALLY beyond-communist" bogeymen everywhere would have been a far more constructive use of your time?
