But as a whole, the religion still tends to agree on certain things, which form the foundation of that religion.
Absolutely, and that's what I'm getting at.
Actually it is - Law is basically derived from the commonly agreed morality, codified and written down for definitive clarity. It also allows for extenuating or variable circumstances, a degree of subjectivity and even revision based on changing society, within that structure.
Far as I understand it, he was jailed for his actions, not his speech.... actions which he admitted were knowingly in violation of orders specifically prohibiting him from doing this.
Speech is free from persecution by the state... but not necessarily by the people. Also, inciting hatred and attempting to pervert, prejudice, influence or otherwise affect the course of justice is a crime, and Robinson has a history of stirring things up like this.
If that were the case, people would have no legal recourse to whine about their "right to Freedom Of Speech".
If you do have it in law of any kind (and you do), it also carries a level of responsibility in how you exercise that right - Namely that you don't use it to damage the rights or reputations of others, national security, public health, public morality or public order. Robinson did this on several counts.
It's not licence to say whatever you like and is only freedom of speech, not freedom from consequences.
