Well your "Club" allows new members and publishes a list of criteria you must meet. The applicant must also pay a, rather hefty, application fee (non-refundable of course).
The Applicant meets every criteria, but is denied. No reason is given since the vote is simply yes / no.
Welcome to the Tyranny of Democracy.
I will admit though that the Lady in question has been less than "model" in her dealings with the community / town council. She is the exception that justifies something more that just a checklist. As I made clear in my first post - that the town council should hear arguments for / against naturalization seems to be the fairest way. Such decisions can be appealed if necessary (from both sides!) if it seems apparent that "due Process" was not given.
It is one of those things that "sounds" good because you can keep out the "riff raff" (even though they are already there, pay taxes and otherwise comply with customs and culteral norms). But you know most "voters" (and they are not different here!!) - they see "John Smith" wants to be a citizen and say yes, they see "Al Jankovic" and say no. There is no thinking or research. Simply prejudice.
Now let's talk about our club. We also have rules of entry. But we also have a club president and his followers that defy the rules of our club and let in those that he wants and allows them to even vote in order to solidify his groups control over the club. But enough of us are fed up with his corruption that we voted in another leader, that will reverse the corruption of our clubs rules. Question: what should we members do to that corrupt former leader and his followers?
