Fun fact: It's actually a misattribution. The quote was actually “First they ignore you. Then they ridicule you. And then they attack you and want to burn you. And then they build monuments to you," said by a union organizer named Nicholas Klein a few years before Gandhi was credited with it.

That said, that's kind of what makes the words work -- they apply to any cause that's had to fight from the ground up. BTC's obviously the epitome of that. But as @Undisciplined noted, everyone thinks it applies to them. The groups that fail at each stage are forgotten. I feel it's more a mantra/self-affirmation (which is fine) than a truism.
