People are being harmed. There are people (let's be charitable and assume that the set does not include TeMPOral) who want to do nothing, because they aren't among the people being harmed.

Then there's a second set of people (let's be charitable and assume that the second set does include TeMPOral) who see the harm, and care about the harm, but are unsure how far to go toward fixing it, because the wrong action (or too much of the right action) can do more harm than good, even to the people you are trying to help.

And then you have the problem that the first set of people are trying to sound very much like the second set of people (and maybe even to convince themselves that they are the second set of people).

No, there isn't. At least not in the examples mentioned.

What you mention is one point of MLK's quote, but my point is different: not everyone who doesn't want to join the fight against status quo is such moderate without a personal stake in the outcome. Some are people who very much care, and have a stake, but decline involvement because they see the proposed means to involve too much collateral damage; the cure to be worse than the poison.
