This begs the question: is this reality? Are people genuinely prepared to resort to extreme measures over trivial disputes? Why can't conflicts be resolved amicably, without the threat of violence hanging over us?
thailand is no different from other countries in this repect, and much safer than many, in the usa for example, a small slight can result in someone getting a gun and killing people, usually at their place of education or work.
in the uk, thankfully with robust firearms laws, looking at someone wrongly, criticising someone can result in a stabbing.
for sure certain individuals around the world need to calm down, and as you say resolve conflicts amicably. i don't have much hope.
