'Girls wear trousers whenever and where ever they choose. Therefore boys should be accorded the same freedom to wear dresses if they want to.'
That's an example of a current controversial speech topic. It does exactly what you want a good controversial topic to do: trigger emotional responses both for, and against it. Schools who require their students to wear gendered uniforms (dresses for girls and trousers for boys) are being actively challenged!
Controversial or argumentative topics teach us to evaluate ideas, to think through pros and cons, and to debate. Because they are often so polarizing, they make some of the very best persuasive speech topics!
Therefore controversial speech topics or argumentative speech topics are those evoking passionate opinions: ones capable of splitting families, friends, communities and countries.
These are the hot topics, the sensitive topics, the ones we're currently working our way through.
Both sides of the debate are often convinced their point of view is right and their opposition's is wrong.
The benefit of delving into subject matter like this is being pushed to consider our own attitudes, values and emotional responses, which in turn helps makes us think more clearly.
Historical controversial speech topics
History gives us examples of topics that once caused major strife. Now with the benefit of hindsight, we may wonder what all the fuss was about. Opinions have changed. What was once dangerous to discuss or even think about has become commonplace: unremarkable and acceptable.
Believing the earth moves around the sun, doesn't even raise an eyebrow now. But in 1633, in Italy, it was a highly controversial subject. The Roman Inquisition sentenced the famous astronomer Galileo to permanent house arrest over it.
Centuries later the abolition of slavery, giving women the vote, and desegregation in schools provoked similarly strong responses.
Modern controversial topics
Like their historical forerunners, these are argumentative or persuasive speech topics reflecting the current political and social issues impacting on, and shaping people's lives.
They can be broad, affecting everybody in the world, for example the global warming controversy (Does it really exist?), or narrow, concerning far fewer people. A good example of the latter are local conservation issues.
For instance in the area where I live there is a current, very lively, debate over land usage adjacent to an estuary.
Should a developer be given permission to close down the much used public walkway on the estuary edge in order to make it easier for his commercial development to go ahead?
Regardless of their reach: global, national or local, controversial subjects draw impassioned debate.
Who is right?
Who is wrong?
And is there a middle ground or compromise acceptable to both sides?
If you want your speech to be the best it can be, what comes next can make or break it.
Your first step is to consider ALL of the following aspects carefully before settling on a topic.
Who is your target audience?
A good speaker always considers their audience and shapes their speech around them.
Think about the people you intend to speak to:
Are they young? Are they older? Are they predominately male, female, or a mix?
What common themes, attitudes, values and beliefs unite them?
What cultural or social backgrounds do they have?
What would be a good topic, one that is appropriate for both them and the occasion? The right topic will genuinely interest them, and will benefit them to know about.
What do they expect from you as a speaker?
What is the purpose of your speech?
Do you want to shock?
Do you want to inform?
Do you want to persuade?
Is it a mixture of all, or some, of the above?
What do you want the audience to do as a result of having listened to your speech?
Research & presentation
An effective controversial or argumentative speech is well
researched. This provides it with a rational, rather than purely emotive, base.
For example: "I don't like XXX.", has no logical appeal at all! It is not an argument.
However, "I don't like XXX for the following three reasons..." , is the beginning of one.
If you want to challenge or change opinion you will research:
the background history of your topic
both sides of the argument - the for and against
You will present:
factual, and if possible, demonstrable evidence or proof
examples
unbiased statistics
and do so in a way that the audience can follow while fulfilling your speech purpose.
And very lastly
Choose a subject that truly interests you. That way your enthusiasm will carry you through the research, writing process, and rehearsal, to delivery.
There are 242 persuasive speech topic ideas below for you to consider, split across four broad groups: food, babies and children, teenagers, and society.
