This is more for the benefit of other PNMs reading the thread than for the OP, but...no selection process in life is completely fair. College admissions and job interviewing are a long way from being completely fair. Legacy policies are quite unfair to unconnected applicants, but they persist because they carry other advantages for the institution. Sometimes people get cut unfairly because the people making the selection are jealous or bitter. It's not fair that good-looking people have a leg up in life compared to ugly people. But it happens.
Groups have a right to use any process they want to choose members, whether it's fair or not. But I think we'd serve all young people better if we don't pretend that things are fair when they are not. Groups STRIVE to be as fair as POSSIBLE. Some come closer than others. But sometimes people get cut from a process and it's not fair at all.
