Violence isn't always immediately recognizable. Some "peaceful protests" are very violent, because of what stupid people do to draw attention to their pet rock political moment.
Take the 2012 Occupy Wall Street movement of 2012 which favored killing American capitalism. In addition to breaking storefront glass and subsequent looting of small businesses, protesters did some taboo deeds in Portland, Oregon. Some of the protesters found police cars and pooped on them.
Such a foul thing was more than a bad boy getting in the face of first responders, they also left them vulnerable to a number of diseases which could debilitate whoever had to clean it up, which in this case, would have been a cop. Liberals thought this merry and amusing, and were oozing attaboys all over the web. It couldn't have been more passive-aggressive, which is approximately the worst chance of communicating a human being can do do..
Feces are the very vector route of such diseases as cholera, amoebiasis (Traveler's Disease), Dysentery (fever, vomiting, bloody stools, abdominal pain), diarrhea (loose, watery stools that can cause dehydration and death to young children and infants,) hepatitis A (Liver disease that accompanies fever, nausea, fatigue, abdominal pain, diarrhea, jaundice, weight loss, and depression,) several parasitic diseases, carcinogenic diseases such as Arsenicosis, Intestinal worms that can cause anemia, malnutrition, or growth retardation in children, trachoma, a disease that has caused blindness in 6 million people already, Schistosomiasis, which can cause infection and damage your liver, lungs, intestines, and bladder. These diseases can be spread before the victim shows symptoms. IOW, side effects can waste its contaminated victim with loss of GI health, cause assorted cancers that can cause pain and death; the loss of eyesight, and loss of immunity to companion diseases and disorders. This is from one of my sources which covers oral-fecal and water vectors (deliverers) of disease.:
17 Diseases That Water Pollution Can Cause
If giving somebody else, namely a hero first responder such a risk, that kind of violence is up there with AK-47s since so many of the ordinary colon microbes can cause diseases to you that you have never heard of until your doctor tells you why you need to get your affairs in order for your heirs and family's future security and hands you a printout of what measures you can take to extend your life a few more weeks.
Some things just ain't damn funny, and I have 12 books on microbiology and their sundry pathologies in my home library that show how serious disease-causing organisms or viruses can be when ignored. The ones from your colon can be quite grim.
