The hardest part about becoming a better person is admitting that you have done the things you hate. You have discriminated, you have excluded, you have used words that you shouldn’t use. It may be out of ignorance but you did those things. 

That’s a painful thing to know, but it’s a bridge we must all cross if we want to be better people. We even have to accept that no matter how hard we’ll try, we’ll make some mistakes along the way. We’ll be bad allies, we’ll discover we have some ignorance left. That’s inevitable, all we can do is cross those bridges when we get to them and become better than that. All progress we make is a thin veneer of good behaviour if we do not acknowledge the mistakes we make and move past them, if we do not acknowledge that we make mistakes today and must try to find them to be better tomorrow.

From that process, we may learn to change the world. We may learn to see those who discriminate and exclude as humans like ourselves. Flawed like we all are. Humans who can be changed and forgiven. All activism is pointless without that.
