1) Knowing his father smokes certain plant leaves
2) Knowing the police kill pets
From the description at YouTube.com:
This video shows a search warrant served by the Columbia Mo. police department. The cops bust in this guys house in the middle of the night and shoot his two dogs (one a pit bull that was caged in the kitchen and the other a Corgi) with children in the home. it turns out that rather than a big time drug dealer, this guy had a small pipe with some resin in it, a grinder, and what the cops here call "a small amount of marijuana" (meaning less than a few grams).
The War on Drugs is a war on children.
You reply, "Drugs hurt children."
Drug use is a symptom of prior child abuse by a hopeless, meaningless, impersonal, dehumanizing system of atheistic government schooling.
