Forster was at odds with Arthur Greiser, who had complained to Heinrich Himmler, the 'Reich Commissioner for the Strengthening of Germandom', that Forster's assimilation policy was against Nazi racial theory. When Himmler approached Forster over this issue, Forster simply ignored him, realizing that Hitler allowed each Gauleiter to run his area as he saw fit. Both Greiser and Himmler complained to Hitler that Forster was allowing thousands of Poles to be classified as Germans, but Hitler merely bounced the problem back to them, telling them to go sort out their problems with Forster on their own. This was a difficult task; Himmler's attempts to cajole Forster to see matters his way met with resentment and contempt. In a discussion with Richard Hildebrandt Forster scoffed, "if I looked like Himmler, I wouldn't talk about race".
