My point was that Goyim can be good people, and maybe the goyim who have “yichus” are better people as a result and/or more connected to G-d, etc.
Another possibility is that yichus only applies to Jews.
But either way, it doesn’t prove that yichus means nothing. (granted, you wrote “means very little”. It is possible that yichus does not mean so much, but I don’t think that is a good proof.)
