That's correct as far as it goes, but it doesn't prove your point. The adopted or kidnapped children were typically those of "renegade" or "Polonized" Germans, so in the opinion of the SS-RuSHA those children were bearers of "German blood." The issue of whether Poles were of kindred or alien blood didn't come up.During the war, an estimated 200,000 Polish children were taken from orphanages, or from their families, and brought to Germany where they were given to adoptive parents to be raised as Germans.
If the German Government had considered the Poles to be of "alien blood", then such adoptions would not have been allowed.

D. Re-Germanization of lost German Blood [Pages 51-52]
Commitment of Poles qualified for Re-Germanization.
The removal of foreign races from the incorporated Eastern Territories is one of the most essential goals to be accomplished in the German East. This is the chief national political task, which has to be executed in the incorporated eastern territories by the "Reichsfuehrer SS", Reich Commissioner for the strengthening of the national character of the German people. In solving this question, which is most closely connected with the ethnoindigenous problem in the eastern territories the racial selection is of the utmost and actually decisive importance, next to the aspects of language, education and confession. As necessary as it is, in the interest of a permanent solution for the German eastern territories, that the elements there of foreign descent should not be allowed to have or to take up their permanent residence there, so it is indispensable too, that persons of German blood in these territories must be regained for the German nation, even if those of German blood are Polonized as far as their confession and language is concerned. Just from these people of German blood, the former Polish State obtained those leaders, who eventually showed a violent hostile attitude against their own German People, be it through delusion, be it through a desired or unconscious misconception of their ties of blood.
Therefore, it is an absolute national political necessity to comb out those of German blood in the incorporated eastern territories and later also in the general government and to return the lost German blood to its own German people. It is, perhaps of secondary importance, what kind of measures are to be taken against renegades. It is critical that at least their children do not devolve anymore to the Poles, but are brought up in a German environment. The re-Germanization however can under no circumstance be carried out in former Polish environments and can only be effected in the old German Reich or in the Ostmark.
Thus, there are the following two primary reasons, which makes the regaining of lost German blood an urgent necessity.
1. Prevention of a further increase of the Polish intelligentsia, through families of German descent even if they are Polonized.
2. Increase of the population by racial elements desirable for the German nation, and the acquisition of ethno-biologically unobjectionable forces for the German reconstruction of agriculture and industry. The task of the re-Germanization of the lost German blood has been embarked upon next within the framework of the evacuation of those Poles in the "Warthegau" who had to make room for the resettlement of Baltic and Wolhynien-Germans.
