I thought it was common knowledge that if you want to stand on a walkway or escalator to stand to the right, walk to the left. Of course, we live outside of a city with a metro so maybe I have a different perspective. I think that people just don't know because it's not something they do on a regular basis. I don't think that people stand on the left to be mean but maybe I'm wrong. 

(NOT) to be condescending and imply that people who really would appreciate if folks would have the courtesy to at least stand on one section of the walkway so that others can pass are really uptight folks who are unable to slow down and enjoy the journey. The fact is, you're trying to excuse your rude behavior (entirely blocking a walkway) by condemning their behavior (complaining about your rudeness). Sorry, don't buy it. Your momma may not have taught you manners, but eventually you're expected to "get it."
Hey! I don't OWN the walkway just because I paid for my ticket into this place! How 'bout I get the heck out of the way!

Maybe you should try asking the people blocking your path to move next time.
