In my view, it is the trickiest topic.

You have to be an eloquent writer in order to prove how can one defend someone's right while opposing his/her stance in the first place? It is not entirely about freedom of expression in which someone demands freedom for expressing their opinion. It is a two tier topic that takes into account both parties concerning the freedom of expression (In favour and against the expressed opinion). One can also link this topic to the notion of universal tolerance and harmony. Hence, it is a broad topic.

Nevertheless, no one knows about the right and wrong approach. Let's wait and watch.
