I'm on the side of Douglass more than Garrison. On the side of MLK Jr. more than Malcolm X. That's been the "right side of history" so far.

You know more about some things than I do, and I know more about some things than you do. I suspect that I may have gained the greater insight into how to persuade people. If you read Crucial Conversations by Patterson et al., nowhere does it say "tell people you know them better than they do and call them fragile when they protest". If you read works on how to run a successful movement that achieves social change, like https://hbr.org/2016/11/what-successful-movements-have-in-common, one of the key steps is "overcome steadily increasing thresholds of resistance", which you don't do by alienating people. If you read psychology studies like https://www.apa.org/research/action/speaking-of-psychology/persuasion you find that reciprocation and consistency are important factors.

You're free to ignore me, of course. Or to judge me in ways that may be right and may be wrong. It's okay; it won't affect my committment to a more just society. Since I'm aware of the psychology, I can mostly counteract any reactive responses I might otherwise be tempted to have.

But you might be discarding some insight that could prove useful.
