Where is your root?

A man with a heavy Jamaican accent entered into Skypeland and started asking us where our "root" was from, particularly in America. I asked if he meant where our ancestors are from, and he said no he was not referring to ancestry. He went on a long and confused explanation that said in the islands people talked about their "root" and we should all know our "root". I was never able to get him to describe what a root is, or where his root was. I tried to tell him where the indigenous peoples in the US appeared to come from, but he was not interested. I tried to talk to him about the ethnic groups in the US and where they had migrated from, and he was not interested. He just kept talking about the "root" and making less and less sense, the longer he talked. He was positive that others in the room were just being stupid or evasive since we would not tell him where our "root" is. Hmm...
