While I agree with the sentiment of this particular quote, I'm not sure that Gandhi is the best person to be held up as a beacon for liberty (much less, libertarianism). See Chapter 4 of The Politically Incorrect Guide to Socialism: [link]
Besides, this work was submitted to #AynRandArt, and, being an objectivist and libertarian, Rand would likely object to the central-planning that Gandhi implemented in India (and which, arguably, contributed to the country's high levels of poverty).
Every account of history - every single one - is biased in some way. This one simply is honest enough to state its purpose up front.
If you had cared to read the specific chapter that I referenced [link] , or Indian historian Gurcharan Das's article (sourced by Williamson in that chapter) [link] , you would see what I'm talking about.
And I said "libertarian," not "liberal." There is quite a difference, you know.
