There is a difference between blaming someone for the actions of a government over which they have little control, and suggesting that it’s possible to work toward a better system. Nobody blamed the Civil Rights Movement for segregation; though they lived in a time when Jim Crow was law, they did all they could to defeat it.

I’d also suggest there’s a difference between acceptance of bad government action, even if you don’t or can’t actively oppose it, and active defense of such action.
