Freedom of expression has its limitation even in the western world, however its application is selective in nature. For example in the UK an individual cannot exercise his right in speaking vulgarly to a Police officer, because he would be arrested on the spot. Article 10 of the European Convention of Human Rights itself recognizes the need for some limitation on free speech. This is applied due to national security, the protection of health or morals and the protection of people's rights and reputation. A person can be sued in court for defamation because there character was assassinated, clearly this shows that speech is limited in the western world. In Austria, if someone denies the holocaust then he would be sent to prison. Children who go to school can be expelled, on the basis of using vulgar language against a teacher or on fellow students, however does that not stop freedom of expression. The western world has a selective syndrome of choosing what exactly is freedom of expression.
