Sizzla is a Jamaican Dancehall star as so many others. Problem is that some of his tracks is inciting violence and even murder against gay men. Even though he promised many European event managers that he would not preform these tracks, he did so anyway and it cause an outrage in Sweden and his concert was cancelled. Due to a large interest it is still back on and the LGBT community is protesting against this yet again.
It is true that the freedom of expression should extend far, but it should not be okay to spread this kind of message. The line between criticism of homosexuality and incitement of violence is not a fine line. It should be obvious when that line have been crossed. There is laws against inciting crimes even if there is no certain group it is aim to, and there is a good reason why it is that way.
The Council of Europe have interpreted the right to freedom of expression to be interfered with if there is a danger to public health and morals, and if it is necessary in a democratic society. Sometimes this is harder to determine than others, but it is clear that Sizzla with his total disregard of the promises to not preform the offence songs is a person who should not preform his music, and that the event managers were in the right to cancel the preformance.
In Jamaica, however, the decision was met with sarcasm and satire cartoons. The clear message was that the type of homophobia Sizzla stands for is completely acceptable to them. This doesn't mean that we in Europe should accept the same type of threatening messages. Although, we may not impose our views on Jamaica, it is still or right to make and enforce our own laws.
