JK Rowling:

We've all got both light and dark inside us. What matters is the part we choose to act on. That's who we really are.

Proceeds to fund fascists

Ursula K. Le Guin :

Fantasy is escapist, and that is its glory. If a soldier is imprisoned by the enemy, don’t we consider it his duty to escape? The moneylenders, the knownothings, the authoritarians have us all in prison; if we value the freedom of the mind and soul, if we’re partisans of liberty, then it’s our plain duty to escape, and to take as many people with us as we can.

(Apparently frequently misattributed to Tolkien. I love his writings but the man was not nearly as based as Ursula Le Guin)

I know this has energy, but I did try to look for a Rowling quote that wasn't some uninspired one-liner that she unconsciously copied from some Disney movie
