Okay or not Okay that is the question!

I don't know if teenagers are allowed to talk politics well I guess they encourage it in my school and I guess they would do it around other schools too around where I live, Canada. I remember in my old school an Iranian school in Dubai we didn't talk about politics with our teachers I though it would destroy my image in front of the teacher I don't know if I was thinking right oh well now I'm in Canada no one cares about this stuff.
So what do you think?
