Under the condition that 8 TGs are in attendance, it's not unusual to legitimately have 0 fitting the demanded demographic. And if you're going to have a Black MtF, a Black FtM, a Hispanic MtF, a Hispanic FtM, that only leaves 4 for other ethnic/racial groups and other TG branches.
Now if 7 of the 8 TGs are non-Hispanic White TSs, someone may make that into a more legitimate beef.
