Articles like this are put in British papers to mock Christians. Take a look at the comments under the article — a large number of them are trashing Christians as stupid and damning Christianity. The articles are simply a way to generate traffic from bigots who want an outlet for their Christian-bashing.
I understand your point but it is the truth there are these people who throw reason aside and fall for snake oil salesmen like this woman. I had come across people like this and you never hear from the pulpit warnings about frauds like this.
They're not making this stuff up.
It's wrong to trash ALL Christians because of the acts of a few, but people who see Jesus/Mary/whatever in shower mold / burnt toast / tree bark deserve to be mocked.
