Any religion and belief can be seen as loony, laughed at or bashed. As well as any religion and belief can be respected. I choose the latter, as long as beliefs I find no interest in leave me alone. Also, I see nothing wrong with people choosing to spend their money at the facility - who are we to judge that it is loonier than spending it to go to competitions, buying expensive gadgets or doing anything else that pleases us?
Looked at the pictures - the place is beautiful, the horses seem happy (why wouldn't they be? They are asked to do nothing, but roam and graze -that's a horsey paradise! :) ) and it seems to attract people who genuinely share these beliefs and find like-minded people there. Shoot me the very day I see anything wrong in that!
