I've explained how Munchausen Syndrome, and Munchausen by proxy, are nothing more than offshoots of sociopathy. Munchausen's requires someone who is utterly dishonest, utterly without scruples, and utterly shameless. In other words, a sociopath.
I've also written about one aspect of virtue signaling which doesn't get a lot of publicity: wearing a prominently displayed cross.
Dee Dee Blanchard claimed that her daughter suffered from leukemia, asthma, muscular dystrophy, among other things. She also said that her daughter was retarded due to her premature birth, and she kept her daughter Erin a wheelchair, even though she didn't need one.
Here's Dee Dee. (She's on the right; her daughter, Gypsy Rose, is on the left):
Gypsy Rose, along with a boyfriend she met online, murdered Dee Dee in 2015.
Kathy Bush is another well known case. By the age of 9, her daughter Jennifer had been hospitalized over 200 times and had had 40 operations. Hospital workers said that Jennifer's condition would inevitably worsen whenever her mother visited. A nurse said that she had seen Kathy fiddling with Jennifer's feeding tubes and IV lines, which would subsequently malfunction. Jennifer was also found to have been given drugs that hadn't been prescribed. As soon as Jennifer was placed in foster care, her condition miraculously improved. (Jennifer now insists she was never abused.) Kathy was sentenced to five years in prison, to be followed by five years of probation.
Her cross is a little more discreet, but still plainly visible.
In each case, the woman seems to be making a statement with her cross: "Look at what a god-fearing, pious, good person I am."
As always, the more virtue signaling, the less virtue.
