Ladies and gentlemen, honorable judges, and fellow debaters, good afternoon. Today, we stand here to argue in favor of the proposition that "People should have the freedom to express their opinions and views without censorship as long as it isn't libel or slander."

Firstly, let us consider the essence of freedom of speech. It is the cornerstone of a democratic society, a fundamental right that allows individuals to voice their thoughts and ideas without fear of retaliation or censorship. This freedom is not absolute； it is bounded only by the boundaries of the law, specifically the prohibition of libel and slander. Libel and slander are harmful actions that can inflict significant emotional and financial damage, and they are properly subject to legal sanction.

Secondly, the ability to freely express oneself is crucial for the development of an informed and engaged citizenry. When people are free to express their opinions, they can engage in meaningful dialogue, challenge the status quo, and contribute to a vibrant public sphere. This is particularly important in a society where diverse perspectives are essential for progress and innovation.

Moreover, the freedom to express oneself fosters critical thinking and individualism. It encourages people to question, to analyze, and to form their own opinions based on the wealth of information available to them. This process is vital for the advancement of knowledge and the development of a well-rounded character.

Additionally, history has shown that the suppression of free speech leads to a repressive society where people are afraid to voice their true thoughts. This fear stifles creativity, innovation, and social progress. By contrast, societies that value free speech tend to be more open, tolerant, and prosperous.

In conclusion, we urge you to recognize the importance of freedom of speech and to uphold it as a fundamental right. It is a right that is essential for the health of our democracy, the development of our citizens, and the progress of our society. Thank you.
