Bump to that.
A lot of Europeans seem to link people group (race) and culture together as if they are the same. In the Shilpa Shetty scandal in the British version of "Big Brother," people were declaring Jade Goody racist because of disparaging comments she made about Indian culture. The two are not the same.
Plenty of Americans use a Germanic language (English) although their amound of Germanic blood may be very low, or nonexistent.
I think the English Isles were conquered by the Germanic peoples(aren't the Norse one of them?)...so there has to be a genetic link.
