This is not a liberal/conservative issue. Adults of all political stripes have allowed this type of behavior to fester and grow.Big protest by the students to-day. According to the CP 24 student interviews, the students all claim it is 120% the fault of the (liberal?) school administration.
BTW: Apparently, this stuff never happens in Singapore.
I am surprised that the parents of these students have not organized a rally/meeting to demand changes.
