You can still be a good person and be ignorant, but you become a jerk when you refuse to acknowledge the ignorance and take the steps to educate yourself through reading, watching, and listening. I’m trying to become less of a jerk, which is about as humble an endeavor as possible. You don’t get brownie points or awards for the act of trying to be less awful. You just get to be less of a jerk, and more helpful. You might also make some more friends.
I believe in the Superhero Sidekick theory of helping, which is to say that if you’re trying to ally yourself with the interests of an oppressed group of which you are not a part, you pull a Robin, not a Batman. You’re not the star of the show, so you don’t direct the mission. You listen, you learn, you assist. You definitely don’t lounge around and wait for the superhero to do all the work and then take all the credit. You also don’t throw up your hands and wail, “WHAT WILL WE EVER DOOOOOOO? THIS IS HOPELESS!” when Batman is right there going, “Um, Robin? There’s like ten things you could do today that would help everybody out. You listening?”
