When you deprive people of their right to live in dignity, to hope for a better future, to have control over their lives, when you deprive them of that choice, then you expect them to fight for these rights.

This quote means that when people are denied the right to live a decent life, have a good future, and have power over their lives, they will usually be driven to fight in order to get those rights back. People need to have some choice in order to feel satisfied with their lives, and when they are deprived of that choice, they become determined to stand up and protect it.
