It seems that CZ is just being fair where they publish blogs and articles in the newsletter that is of interest to some of their members. I personally don't agree with Urine Therapy(I think it's disgusting, unnecessary, and unbeneficial to one's health), BUT there are some people who do. I support intestinal cleansing, but there may be some who don't. However, intestinal cleansing has had its fair share of articles in the CZ newsletter as well.
The newsletter features reading that you can find on the CZ website. That includes Uring Therapy. I don't see why you would be offended by the article that featured it; just don't read it.
