Dangerous Ideas

"The philosopher Bertrand Russel (1872 - 1970) once observed that 'In most countries certain ideas are recognized as correct and others as dangerous. Teachers whose opinions are not correct are expected to keep silent about them.' What opinions, if any, are teachers in your country expected to keep silent about, and to what extent can thsi be justified?"

In my country there are no ideas that teachers are expected to keep silent about. The only ‘’rule’’ is not try to impose it. They can talk about abortion and say what their opinion is, they usually ask us what do we think and that’s all. Religion is another thing that there is no problem in talking. It is not something that we discuss all the time, but it is not avoided, mainly because we don’t have that many different religions. If it is a catholic school, the teachers are nuns or priests so it’s their option not to talk about it.
In the end teachers can say whatever is their opinion but they cannot promote it and say that this is the right thing. And I think this is the best way of doing it. Each person has their own opinion and the rest need to respect.
