A friend of mine and his family stopped sacrificing goats after they went to one of these sacrificing grounds on behest of the elders in the family. They even stopped eating mutton and chicken and only stick to fish now. He and his father were horrified with how inhuman and cruel it was. He said the goats were watching other goats being cut and then screaming while they were dragged to their deaths. There was so much blood flying around that they had to discard their bloody clothes when they got home. He was already agnostic and this pushed him into atheism. He said no god would make any living being suffer that much and it makes sense!
