For the most part, Scientologists are oblivious to how they're perceived outside of their own little bubble world. Sort of like blue state liberals.
I have a very good friend whose parents were "into" Scientology for many years. They spent untold thousands of dollars, and finally kicked her out of the house when she was 16 because she would not follow the Scientology program, on the instruction of their Scientology superiors. She went through incredible hardship trying to support herself at that age.
The philosophy of Scientology, as understood and expressed by her parents to her (and still to this day) is the epitome of selfish hard heartedness. Any trouble she may have (such as a disabled child, and severe asthma) are her own fault, she "created" them. Her very wealthy parents offer her no financial, emotional or personal support whatsoever, and in fact still use her at every opportunity.
