I think its more subtle than idiocy. She isn’t particularly dim.
It is an excellent example of how worldviews become un-mooored from reality. Surely the many people who posted supportive comments to her initial complaint never noticed that it had actually turned out to be unfounded. And they go on to repeat this story to others. The story is that she is getting screwed by obamacare, the reality is that she is getting super cheap coverage (actually I think she has a job again that has benefits, so was). Basically she told the story her friends want to hear very loudly, but was very quiet when the reality didn’t match the worldview.
