And We're Dissin' Them

"Forced out - brave and mighty
Stolen land - they cant fight it
Hold on - to pride and tradition
Even though they know how much
Their lives are really missin'
and we're dissin them
On reservations
A hopeless situation"

How are we, as listeners of Anthrax, to interpret this line in regards to Native Americans\Indians? We as a society are dissin' the Indians and that is bad, or we as in Anthrax are dissin' the indians for not standing up for themselves? I always thought there was some ambiguity there. It seemed like a pro-Indian message overall, but that dissin' line I always took to mean a criticism directed at the indians, but perhaps not.
