Homeopathy is the system of using extremely dilute solutions of the disease-causing entity itself to treat the disease. This is not the same as vaccination, although it may sound similar. The system was developed (made up, really) by Samuel Hahnemann in 1796 well before the germ theory of disease was elucidated. Thus he can be forgiven for his beliefs and his misguided attempt to cure. But no such forgiveness should be extended to those in the 21st century who willfully ignore the advances and benefits of modern medicine.
