One thing I feel you should consider amending: If people of colour and/or other minorities are making a solid point about you just showing up now, “[I’M] HERE NOW AND THAT’S WHAT MATTERS” isn’t really the most productive stance. You’re here now, but it will only help you to consider why you weren’t showing up when they were actually dying. Sure, it may be uncomfortable to think about, but the self-examination is important for personal growth. Let it be the voice in the back of your mind that keeps you showing up for causes outside of your own self-interest.
Otherwise, I thought this was great. I didn’t come here to shit all over everything — that statement really stuck out to me, though.
