Common crossover GCSE question (appears on both higher & foundation papers)
Two key facts to remember:

History calls people “heroes”.
Their contemporaries often called them “difficult”.
Moral courage usually isn’t recognised until it’s no longer threatening.

It feels awkward, lonely, inconvenient.
That’s usually how you know it matters.

Moral courage isn’t just defiance — it’s humility. It requires the strength to confront uncomfortable truths, whether they come from our enemies or ourselves. Listening, when pride urges us to speak, can be the bravest act of all.
