Why do mainstream medicine apologists attack colloidal silver?

Colloidal silver is extremely dangerous. They used to think it could cure everything, but it actually cures nothing, it might have a placebo effect but it's doing more harm than good. Search google images for the blue man or colloidal silver skin, and you will see that it makes your skin turn greyish then bluey grey. All of the silver is toxic and building up inside you. If it makes your skin grey, it is also damaging your internal organs. Unfortunately, this damage is slow to undo itself or you may just never go back to normal (like the blue man). Colloidal silver is a scam and is extremely dangerous, the scammers selling it prey on people who want a miracle cure for all sorts of ailments and don't bother to do a quick internet search to see if it is safe or not.
