Well fair play, I guess you could interpret tired in two ways, phycially or as Parks hereself said in her quote you posted tired of giving in. Second if being secretary of her NAACP chapter makes her a grand civil right leader fine, I challenge you to name a single other secretary from a local chapter beyond Parks, again I think history just has an ability to Monday morning quarterback. And fine maybe any member of the NAACP can be considered a grand civil rights leader, that's subjective anyway, my comment is replying to someone who believes protests must include the middle class to be successful, I believe history suggests otherwise and if you want to identify Parks as middle class too, fine I don't care to argue the point.

Here is a pretty famous Parks' radio interview from 1956, I'll just say I have listened to it for inspiration for sometime and will continue to do so, I may not know much, but I know her own words well, and I just don't think this was some grand scheme she was cooking up for sometime as a leader of the NAACP;

>The time had just come when I had been pushed as far as I could stand to be pushed, I suppose [tired] They placed me under arrest. And I wasn’t afraid. I don’t know why I wasn’t, but I didn’t feel afraid. I had decided that I would have to know once and for all what rights I had as a human being and a citizen, even in Montgomery, Alabama.
