I've been an activist for decades and during that time I've grown incredibly cynical. A lesson that gets repeatedly taught is the vast majority of the loud voices in a movement are smug cowards.
They don't actually care all that much about their cause: you never see them putting in anything resembling work. Sure, they'll throw a few bucks at a cause, maybe they'll attend rallies or protests. But they disapear as soon as anything that requires actual effort, risk, or serious time commitment comes up.
And they sure as hell won't make hard choices that might impinge on their idealism. They don't know how to and are unwilling to get their hands dirty and actually fight -- moral purity is more important than ugly, imperfect, but net positive change.
They'll scream about how they're waiting for a perfect solution ... but they can't be bothered to bust their ass to make it happen. They're dead weight.
