It may be off topic, but I've just made a short comment related to those experimental gismu, and voted down:
"I feel alienation seeing that only American major tribes have their own
gismu. There are too many tribes in the world to let them occupy the
limited gismu space. Please think of creating lujvo instead, or
cmevla/fu'ivla may be enough for them."
Although I said that, I don't hope much that the Lojban community could evade this kind of unconscious discrimination. I know that the majority of this community are Caucasian males. I'm only a minority in both race and gender, and much familiar with such treatment in my real life.
