Absolutely. Everyone involved with the movement put aside their differences to focus on the same goal.
It would not have been as successful if everyone showing up for a rally was expected / coerced into supporting other political issues.
A universal appeal to shared humanity is an approach that works. Shaming people into a type of morality will only invite pushback.
"In 1964, in a poll taken nine months after the March on Washington, where Martin Luther King Jr. gave his “I Have a Dream” speech, 74 percent of Americans said such mass demonstrations were more likely to harm than to help the movement for racial equality. In 1965, after marchers in Selma, Alabama, were beaten by state troopers, less than half of Americans said they supported the marchers."

Compare this to today's thoughtless and abrasive slogans or the writings of today's favored thought leaders on this and how divisive now only are the ideas but the tactics being used to coerce people into compliance.
So yeah, people at the time may have had a distaste for some of the tactics but the messaging was very popular. The riots that took place later on in the decade were a disaster and led to a new, mainstream form of conservatism led by Nixon.
That strikes me as a level of nuance that is frankly unlikely.
I don't think these landmark legal events occurred because people demonstrated so much what the man and his supporters were saying. I believe people miss the forest for the trees and think if they just get a group of people together they're somehow right or will get their way. But it's about what you have to say and how you say it that matters. Peacefully organizing is a great vehicle for that but you still need the goods.
The violence that happened in the later 1960's set so much of it back IMO.
Yet your conclusion is far too final: it's not a "myth" that people didn't support these changes; some people did and some didn't, as with anything. At one point in the end of 1964, a majority of people oppose the protests that led to these changes.
And in fact, the 24th Amendment faced substantial opposition from southern states; I'm not able to find contemporaneous opinion polls (and I'd be interested if you have any), but it's far from the case that it was without controversy!
I strongly disagree with your last line, however—not because violence is acceptable or productive, necessarily, but because your interpretation exculpates reactionaries who regrouped and pushed back against such changes, which I think is a highly relevant lesson for the Trump era:
Race is such a good predictor of a vote for Trump. The simplest explanation for Trump's rise is that he is a counterreaction to the election of the first Black President.
So too with the success of a cynical Southern Strategy following on the heels of the Civil Rights Era.
However, opinion polls _do_ show a _correlation_ between support for _BLM_ and coverage of demonstrations: https://fivethirtyeight.com/features/support-for-black-lives....
You could still support the Civil Rights movement, but believe that mass demonstrations harm it.
Those two things are completely separate.
not 'all of us'
When you ask a question like that, what you're really asking is, "why don't workplaces have the outcomes I expect along racial lines when it comes to hiring, compensation, promotion, and more?" And implicitly, "why can't workplaces be forced (or force themselves) toward meeting the outcomes I expect?"
Those are different questions, but they're encoded in yours. And they don't really apply to the topic at hand.
