We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
I doubt it's a deliberate scam. I suspect she is not insane, but probably half-crazy. It's easy to prove: just do some blind testing of her.
It reminds me of Multiple Chemical Sensitivity (a fascinating article). People in the US can retire on this non-existent syndrome. The shame is that quacks are around to reinforce this sort of nonsense:
"Multiple chemical sensitivity" is not a legitimate diagnosis. Instead of testing their claims with well-designed research, its advocates are promoting them through publications, talk shows, support groups, lawsuits, and political maneuvering (such as getting state governors to designate a Multiple Chemical Sensitivity Awareness Week). Many are also part of a network of questionable legal actions alleging injuries by environmental chemicals.
Many people diagnosed with "MCS" suffer greatly and are very difficult to treat. Well-designed investigations suggest that most of them have a psychosomatic disorder in which they develop multiple symptoms in response to stress. If this is true—and I believe it is—clinical ecology patients run the risks of misdiagnosis, mistreatment, financial exploitation, and/or delay of proper medical and psychiatric care. In addition, insurance companies, employers, other taxpayers, and ultimately all citizens are being burdened by dubious claims for disability and damages. To protect the public, state licensing boards should scrutinize the activities of clinical ecologists and decide whether the overall quality of their care is sufficient for them to remain in medical practice.
Lyme Disease (which is a real and readily-treatable infection) presents another interesting situation in which crocks and quackery abounds.
I know somebody who supposedly had MCS - lived in a bubble with a really expensive air conditioning system to scrub the air - went outside in a full environment suit - only ate vegetables that were "organic" and non-chemically altered by whatever.
The interesting thing is that one of his relatives had quite enough of this nonsense so she did some fancy switching and down right skull duggery to introduce unwashed veggies and various chemicals into his bubble home. When nothing happened after a month or so, she told him and he went absoutely berzerk - and about a week later was walking around normally and eating Big Macs at McDonalds. Probably not the best way to treat it, but it works.
On the other hand, I have a severe allergy to new carpet. I had to live outside the house up North when we recarpeted the house about twenty years ago. Took about a month to get the chemical smell down to something bearable.
