Just as Communist wealth redistribution schemes take wealth from those who have more and redistribute it across society so everyone has an equal share, so does Spirit Link Totem take health and redistributes it evenly among your party or raid so everyone has an equal share. Thus, it is fair to say that Spirit Link Totem is Communist.
To remind everyone of the glorious power of Spirit Link Totem, I use the following macro to announce to my raid when I drop it:
/cast Spirit Link Totem
/yell FROM EACH ACCORDING TO THEIR ABILITY TO EACH ACCORDING TO THEIR NEED
Go therefore, and do you likewise.
