One of the things I'm really enjoying about Mastodon is that, since it's still so new and small, it's very easy for me to cut out passive aggressive/inactive writing from my timeline swiftly.
Where I'm at with my activism and energy at this point in my life is that if I've got a problem with someone, I talk to them. This goes well with a FOSS project like Mastodon, where dev work is visible and maintainers are accessible and responsive.
Folks just kinda blastin' into the federated timeline...good for you I guess? But I mute you and question the person I follow who channeled you into my life.
TL;DR don't argue with people who aren't there, kids!
