The analogy [sic] does not hold. It is tantamount to saying that a mountain spring and a sewer are equivalent because both contain liquids. The fact is that urine can be drunk or used to treat wounds, as it is antiseptic (unless the urinary tract is itself infected by opportunistic bacteria, as in the common STDs, urine is sterile). So the original poster's comment cannot be reduced to a de gustibus argument. (I do not mean to turn this page into a group therapy session, I am simply contributing this comment as a corrective since what we write here has an impact upon the article itself.)
