Ew. Why do people want to live in these fantasy communities?
This kind of thing reminds me strongly of how the main difference in quality of educational experience between public and private schools is that the private schools can be self-selecting. They can tell problem kids and families to hit the road, while offering them no solutions for whatever is wrong that hampers their participation in a productive school experience. Public school kids are expected to excel and learn in a truly inclusive community. There are kids who can't speak English well, or have speech impedements (or maybe they mumble because they have a piercing, lol), or are below average or disabled in some significant ways. Some kids (and their parents) just plain don't know how to act right. Everyone (and their teachers) must accommodate diversity. People are only expelled if they take the most extreme risks or cause serious harm. Nobody is expelled for stealing a can of pop.
I feel very turned off by "gated communities" of any kind. I definitely see the appeal of wanting to live in a private home where people are only welcome if the group is better with them than without them... and on a household level, I do think it is an ethical way to live... but for a greater community? I find it very icky and lacking in basic compassion. Plus, I seriously doubt any real diversity is possible when you have a like-minded group choosing who can come and who can stay, etc. They seem just as icky as the people who won't let you live in their neighborhood unless you can afford a $500k house and agree to paint it beige and keep your grass trimmed just so, etc.
I get what the FAQ is about, but put it another way: what if you went on a first date or just met an attractive person and they handed you a FAQ explaining what their expectations were and what yours should be if you two start any kind of relationship, you'd think that person was socially awkward at best.
Unless they have disabled people, families with kids of all ages, elderly people, people of all races and sexual preferences (including monogamy, certainly!), they are kind of just playing make-believe and turning their backs on the reality of American life today. I'd rather work to make the real world a better place than recede into fantasy and start excluding anyone who is inconvenient to my personal goals, etc. I mean, we are all connected. What happens to their little commune if SHTF all around them? I don't think what they are doing is sustainable because it's based on conveniently excluding people who don't fit their ideals. What do they do when one of their long-time residents becomes disabled or just too old to carry their weight? What if a couple has a baby and it is very below average in ability (maybe requiring expensive medical care)? Sounds like a fair-weather community and from all I'm hearing, we have hard times and rough weather ahead.
Good luck, self-selecting teeny tiny community! At least they can rest assured the regular-old everyday American community around them will accept them back with open arms if they fail to keep enjoying their little elitist group thing.
