Let's say you live in an apartment building and your landlord locks you out and keeps you belongings. Police say its not their problem. Courts decide that they don't aare either. So now you have no recourse or body to complain to.

In that situation saying "i resolve problems non-violently every day" stops being relevenat. The mechanisms that allow you to do so (enforcement, law, etc) have been removed as they were for those fighting for civil rights.

You may still personally choose non-violence in this case, but I'd bet you would understand/sympathize/maybe-even-join those who decided to break into their apartments by force and grab the things that are rightfully theirs.

nobody is secretly violent ... just normal peaceful channels stoped working.

Recognizing that distinction isn't justifying violence its just explaining why nonviolence provides leverage in the first place

I've listened to a lot of Malcolm X. He was a better speaker IMO, his rhetoric was better. I believe he had a more accurate understanding of the reality of how power really works. It has nothing to do with wanting to justifying violence, Malcolm X made a number of matter of fact observations.

I think the specific condition here is "change that someone else is willing to prevent using violence". I guess that is not present too often during everyday life.

Everyday you're not trying to achieve political change.

And a lot of those interactions are backed by implied violence: people paying for things at stores is not because everyone has actually agreed on the price.
