@esmith you drawing parallels between this propaganda and your "vitriol" is not real evidence. It does not prove your point and as I pointed out it is a straw man argument; also the link you provided was not based on a real study (I looked at the "study").
I don't care about your
news articles that are littered with ads and I don't care about your subjective parallels. Show me a real academic study proving your "vitriol" (not something else) causes an increase in violence. Furthermore account for the difference between people who are violent and those who are not. If it truly causes violence in people, then why not everyone?
However, I can tell you right now there are no valid scientific studies that will prove your "vitriol" as a cause of the violent behavior since it is not something that can be randomly assigned (you need RA to establish cause), and the massive difference between the non-violent and the violent will always raise the issue of confounding variables. What causes one person (or even a few people) to react with violence while the majority does not? Likely there is something else going on with that one person.
