I dont understand why I continue to respond to an obvious mental midget.
When you make a definition that broad you include virtually everybody in some kind of "ethnic" group or other. So on that basis, Lutherans constitute an ethnic group. Members of a condo association constitute an ethnic group. Virtually any group that shares any characteristic that distinguishes it from other people would constitute an ethnic group.
What a ******* loser.
Because you are incapable of discerning who is and is not a mental midget based on your own limitations.
I did not make the definition. Here is another:
Oxford English Dictionary
Ethnic
a[djective]
...
2.a. Pertaining to race; peculiar to a race or nation; ethnological. Also, pertaining to or having common racial, cultural, religious, or linguistic characteristics, esp. designating a racial or other group within a larger system; hence (U.S. colloq.), foreign, exotic.
b ethnic minority (group), a group of people differentiated from the rest of the community by racial origins or cultural background, and usu. claiming or enjoying official recognition of their group identity. Also attrib.
n[oun]
...
3 A member of an ethnic group or minority. orig. U.S.
—Oxford English Dictionary "ethnic, a. and n."[23]
Unlike Lutherans, Jews also defined themselves through matrilineal heritage. Unlike your condo association members - Jews do share a distinctive culture, religion and even language.
You can't have it both ways - you can't define yourself as an ethnic group for the purposes of minority protections against discrimmination on the one hand yet claim not be an ethnic group for the purposes of denying those same protections to another group by trying to claim they are all the same.
It amazes me the lengths you will go to defend a system that is inherently wrong.
