I understand the sentiment here, Beth, but can't agree with it.Righteous indignation becomes anger and hatred when no one reacts to the righteous indignation.
For example, the "othered" in our society (people of color, LGBTQ folks, women, immigrants, the disabled, the mentally ill, etc.) have expressed righteous indignation for decades and nothing improved. They were ignored and blamed for circumstances not of their creation.
How long does one be righteously indignant? Until death? Then, what good does it do?
Tragically, no one pays attention to righteous indignation until it becomes anger and hatred. Until a limit is reached and a line is crossed. Until we won't accept today what we accepted yesterday.
Truth is half of our country hates the other half. Truth is one half of our country doesn't much care what happens to the other half. Truth is half of Americans refuse to do what it takes to contain a virus. Trust is half of us are against science and education and equality.
Yes, I am simplifying. But, really, is it that complex? I don't think so.
At some point, you either get angry or you give up.
