Lol ok, since you want to be pedantic, let's really get into some details, because you're just wrong about MLK to start.
Civil Rights Act of 1964
How did it happen? The Civil Rights Movement itself was largely nonviolent, with most of the violence happening towards protestors. Figures like Martin Luther King Jr. emphasized civil disobedience, boycotts, and peaceful protests.
Women suffrage
Though some suffragettes engaged in civil disobedience, the broader movement relied on lobbying, protests, and legal appeals. That was the bulk. What you're calling out is one offs and trying to act like that was the norm or bulk of the movement. It was not.
Marriage Equality
Obergefell v. Hodges Supreme Court decision legalized same-sex marriage nationwide. No violence needed.
Disability Rights Movement, also known as the ADA
Advocates lobbied for equal rights through demonstrations and legal battles. This resulted in the ADA being passed in 1990
The Fair Labor Standards Act (1938) – Ending Child Labor & Establishing Minimum Wage
Labor unions and activists pushed for reforms through strikes, negotiations, and legal battles.
The Voting Rights Act (1965) – Protecting Minority Voter Rights
The Selma to Montgomery March and other efforts, led by MLK and civil rights groups, put pressure on the government.
Title IX (1972) – Gender Equality in Education & Sports
Women’s rights activists lobbied for equal educational opportunities. This endned gender discrimination in schools receiving federal funding, revolutionizing women’s sports and education.
Don’t Ask, Don’t Tell Repeal (2011) – Allowing Open LGBTQ+ Military Service
LGBTQ+ advocates, veterans, and lawmakers worked for repeal.
So while you'd argue I'm being naive, I'd argue that you're not informed enough about the topic to make such statements. Especially such absolute statements like "every American movement has used violence" when that is objectively wrong. I don't remember the great Marriage Equality rioters killing people, or the War of Don't Ask, Don't Tell.
Please stop spreading misinformation.
Edit: lol some people are mad that facts don't line up with their world view.
