Nonviolent methods often require the possibility of violence as a backdrop to be effective. Otherwise, they might not yield the desired results.
While Gandhi's philosophy sounds nice in theory, it may not always be the most practical in real-world scenarios.
That is why the GP put the "evolved" in quotes. It takes something more than the basest human instincts and the animal sides of us to take this approach. Some may consider it naive. I personally think Gandhi was smart enough to deduce this on his own yet still chose the nonviolent approach regardless. That alone shows he was a greater "man" than most, in my opinion.
The historical record says otherwise:
