How is burning a book an example of "free speech"? Its not speech, its a physical action.
free speech is a Common Law concept, in Continental Europe they typically use broader terms which makes it either less relevant or irrelevant whether something is speech or another way of expressing an opinion. German has Meinungsfreiheit (freedom of opinion), Spanish and French have libertad de expresión and liberté d'expression (freedom of expression), and the Scandinavian term yttrandefrihet (Swedish) and ytringsfrihed/t (Danish/Norwegian) also means freedom of expression.
