I have never said that all R-U106 are proto-germanic, I just said that the proto-germanic were a group of R-U106 carrier who settled in Scandinavia and were the trigger of the birth of the germanic culture, then the first germanic people was an hybrid between I1, R-U106 and R1A and were scandinavians.
The other U106 carriers who were more lately germanized, spoke celtic languages before.
