Perhaps, but he also made a gratuitous jump from "association by a common sense of right" to one "connected country [given] to one united people-a people descended from the same ancestors, speaking the same language, professing the same religion".
Among the conservatives, there is no disputation for a need of common language and a common sense of rights. There is a difference of opinion though as to the importance of common genetic source, so I focussed on that difference alone.
