Actually, the person's name is listed as the creative designer/director for the haunted house and for the fetish site. You can pull up the site for the haunted house or the fetish site and find the same name taking responsibility for the creations at both places. The similarities are very close and it appears that some of the pictures are the same or have the same background, at least from what I can see of the samples.
It's not that I am against freedom of expression or whatever that would be considered, but I have a problem if a charitable name is being used as a front for it. However, I don't want to get caught up in it and I am hoping that it is purely just a coincidence or an oversight. I really hope that it isn't being used in that manner.
In addition, I don't think it would be appropriate for children. As one poster said, a child does not need an additional reason to be afraid of the hospital or doctor's office.
