In the European Union (EU) ‘Freedom of Speech’ is a Legal Right, subject to the usual legal restrictions such as slander etc. These rights to ‘Freedom of Speech’ are enshrined under Article 10 of the European Convention on Human Rights.
However, under EU law it is also recognised that with the ‘Right’ to ‘Freedom of Speech’ comes ‘Responsibility’ e.g. as covered by the ‘Hate Speech’ laws specifically to prevent incitement to violence against minority groups e.g. Jews, Muslims and homosexuals etc., who tend to be the more vulnerable sections of Society and who (in a responsible society) need legal protection against prejudicial discrimination. The laws governing ‘Responsibilities’ on Freedom of Speech are there specifically to discourage things like racism, xenophobia, anti-Semitism and intolerance against Muslims, through incitement to hate.
Specifically, in the United Kingdom, it’s a Criminal Offence under hate speech laws to make communication which is hateful, threatening, abusive, or insulting and which targets a person on account of disability, ethnic or national origin, nationality, race, religion, sexual orientation, or skin colour.
However, I am aware that many outside of the EU don’t understand our ‘Hate Speech’ laws and view it as a ‘gaging’ of free speech; whereas in actual fact it’s not. The laws are there purely to protect the vulnerable against prejudice and incitement to violence resulting from hate speech; and are not there to gag one side or another from expressing their views. Keeping within the laws, while expressing your views isn’t that difficult (unless of course you are xenophobia or racist), it’s just a case of choosing your words carefully so as not to incite hatred. And the bonus is that people of opposing opinions can have a more productive civilised debate rather than a destructive shouting match.
All debates in the British Parliament are televised and freely available for viewing on YouTube, so to see how civilised political debates can be, as MPs use their Freedom of Speech responsibly (and with respect), you only need to view the videos published on YouTube.
