"so hence we should kill teachers to get the system to continue to perpetuate eternally. To me, this is not a matter of retaining teachers anymore. It is a problem with being a slave of the idol of money"
"just block em and nuke em"
A commentary on the Singaporean education system being unsustainable because it relies on paying teachers more (even if they still burn out) instead of more sustainable solutions is interpreted as calling for teachers to be killed.
Saying you should nuke cyberbullies is also non-kosher (apparently civilians have easy access to nuclear weapons, so this is clearly a threat too).
