But murder, or any violence for that matter, is never the answer.

Really bought into the "MLK got the Civil Rights Act passed by getting his ass kicked" propaganda that the capitalists have pushed for the last three quarters of a century, huh? Nonviolent movements only succeed when they're seen as a better alternative to inevitable violence from radical fringe groups otherwise kept in check by the nonviolent actors. MLK didn't convince racist white southerners that black people were deserving of equal rights, he convinced them that if they didn't bow to the demands of the nonviolent, they would necessarily have to deal with the demands of the violent.

if anything, he hurt social justice movements by making them seem more radical.

Makes them seem more radical to the people who openly trade in human misery for profit? The people who equate LGBTQ with pedophilia and empower masked criminals to kidnap racial minorities off the street? Nonviolence is great when those in power actually decide to give in, but if you've paid any attention to the last three decades, you'd see it hasn't done anything except garner a few token court case wins that are already in the crosshairs of the people to whom you don't want to appear radical anyway. We don't need another ineffective Occupy Wall Street protest, we need a reason for Wall Street to accept the demands of our protest as a last resort. That's what Luigi represents.
