>You? Only people that politically agree with you?

the next sentence after they mention "necessary trouble" is literally:

"But that only goes as far as to be my opinion."

they are just stating their opinion.

everyone decides when the time for "necessary trouble" is individually, based on their accumulated experience, opinion, etc. no arbiter required, just a critical mass of people with aligning opinions.

Who was the arbiter of the trouble necessary for gay rights? Who was the arbiter of the trouble necessary for civil rights? Who was the arbiter of the trouble necessary for womens' rights? Who was the arbiter of the trouble necessary for the rights of handicapped people? Indigenous people? Immigrants?

American society was created for the benefit of straight white Christian men alone. Every right held by any other group, every ounce of political power, every bit of basic human dignity, has had to be taken by force of "necessary trouble." There is no "arbiter." How could there be? An arbiter presupposes an objective moral ideal and a just society, neither of which we have.
