B2 has been mentioned several times as Exhibit A of insidious colonialist ideology lurking within D&D. This is from the introduction:

The Realm of mankind is narrow and constricted. Always the forces of Chaos press upon its borders, seeking to enslave its populace, rape its riches, and steal its treasures. If it were not for a stout few, many in the Realm would indeed fall prey to the evil which surrounds them. Yet, there are always certain exceptional and brave members of humanity, as well as similar individuals among its allies - dwarves, elves, and halflings - who rise above the common level and join battle to stave off the darkness which would otherwise overwhelm the land.

It could be a lot worse? Right from the intro, the PCs are presented as defenders, not conquerors.
