its important though to seperate the 'look' from the actual circumstances. Was he anti-indigenous, did he kill indigenous Peruvians deliberately because of their ethnicity, or because some were fighting on the side of landed interests?

Lots of bolsheviks were Jewish, of course that doesn't mean that in killing Russian opponents they were carrying out an anti-Russian campaign - although that is a common rightist accusation, presumably because of how it 'looks'.

As far as I understand Peru, a lot of the rural areas have indigenous populations, partly because many fled there during the European conquest. I don't think it is possible that the resistance movement could have done what it did without the support of a large amount of indigenous people. Of course, some will have opposed the communists - the armed militia, referred to as 'peasant patrols' seem to me to be paramilitaries assisted by the state and fighting for landowners, particularly cattle ranchers.
