Yes...as in all such things. Is it wrong to try to measure UK laws by our standards? Or is that the American way of global hegemony?A bad thing....here. We have secular laws that protect us from that.Because the UK doesn't have the Bill of Rights. duh.In your country, he would be arrested, and you would support it.
Do you think jailing people for political differences is a good thing or a bad thing?
That's an odd way to look at it. It is only wrong here because of the Law?
If discussing Rights from an American perspective is hateful for you, I'm happy to discuss it in the context of the UN Universal Declaration of Human Rights.
From that perspective,( much like from the American one ), Human Rights are inherent and inalienable.
Thus a law that empowers the UK government to imprison someone for simply having the wrong political opinion, or expressing said opinion,
is a violation of Human Rights and thus unjust and morally wrong.
FYI
