A short, finished list rather than an endless feed: 100 of the best equality quotes ever written, picked out of the full equality archive on QuoteForever. You will find Henry Rollins, Michelle Bachelet, Susan B. Anthony and Malala Yousafzai among them.
Read the list top to bottom, or use it as a starting point - every author name links to everything else they said, and every quote has its own page you can share or turn into an image.
