Lol. No they aren't. The people who are currently hopeful and optimistic are okay with slow progress, which isn't nearly fast enough anymore.

The people who started the french revolution vs their king were scared and had hatred for their rule, MLK and his followers were scared and hated the oppression.

Hopeful and optimistic people don't want change because the status quo is working great for them.

There is the threat of falling into authoritarianism. But that's always a threat as the US government is showing now with our shitty recent Supreme Court decisions.
