Being a teacher means that I used my voice a lot & also was often exposed to childrens infections. Every time I got a cold it turned into something worse, laryngitis, strep throat, bronchitis, pneumonia & pleurisy. Even now I'm retired I don't seem to be able to just get a cold & I often lose my voice. As I live alone & don't talk to myself much - yet, it isn't a huge problem.
But communicating & speaking is an important part of our lives. Our relationships & our work lives depend on it. Today we can communicate through other means, text & email for example. But they are open to misinterpretation in a way that speech isn't, because there are context clues with speech - tone of voice, facial expression & body language for example.
However that isn't really what I'm thinking of in this post. I'm thinking of the voice that we each have to influence other people & big decision making. I think that we forget that our individual opinion can be really important in the areas of politics & philosophy. If we speak out individually in social contexts we may or may not influence what others think. But if we disagree with a point of view I feel that it is important to be able to express it. Unfortunately it is often the case that we don't speak out for fear of offending or upsetting others. Or we just aren't confident or brave enough. But letting an unacceptable point of view pass is colluding with the speaker. It's actually cowardly.
People have fought for the rights of free speech. People have fought for the right to vote. People have fought for the right to be part of a collective like a union or professional organisation. One voice in the wilderness may not have much of an impact. But protests & marches can be powerful demonstrations of a groundswell of opinion that should not be underestimated. That is how change for the better happens. Think of Votes for Women, LGBT rights, Grenfell & safer Homes, the Right to Roam, Apartheid, Fracking....
Our right to protest, which is central to a healthy, functioning democracy, is under threat. The police have huge powers to restrict protests and arrest demonstrators under the Crime and Policing Bill.

Having a voice & using it is very important. Use it or lose it. Losing your voice means far more than being dumbstruck. It means losing your power to affect change for the better.
