On Tuesday, Ashton Kutcher posted an emotional video on his Instagram TV (IGTV) account captioned, “#Blm vs #Alm – understanding why saying ‘all lives matter’ is missing the point. #blacklivesmatter.”

He began his video saying, “So, on Saturday, I posted a black out of my social media channels and just posted ‘BLM’ and a lot of folks responded, ‘All Lives Matter.’ And, I want to talk about that a little bit because I don’t think the people that are posting ‘All Lives Matter’ should be canceled. I think they should be educated.”

Kutcher shared a moment he experienced with his wife, Mila Kunis, and their two kids which inspired him to post the video and speak on the topic. The clip spans just over two minutes.

“We all agree all lives matter. But I had a really poignant experience tonight when I was putting my kids down to bed that lent the words for why black lives matter. So, usually Mila and I put our kids to bed and we read them a book and our daughter always gets to go first. And tonight, as we were reading her book, my sons says, ‘Wait, why don’t I get to go first?’ And Mila said, ‘Because girls go first.’ And he said, ‘Yeah, but boys go first.’ And I looked at him and I said, ‘No, girls go first.’ And I said, ‘You know why girls go first? For you and me, girls go first. And the reason why is, for some boys, girls don’t get a go at all. And so for you and me, girls go first,’” Kutcher said.

He concluded his video: “So when it comes to Black Lives Matter, I think what folks that are writing ‘All Lives Matter’ need to understand is that for some people…black lives don’t matter at all. So for us, black lives matter. So, while you may have the best intentions in saying, ‘All Lives Matter,’ remember: for some people, black lives don’t matter at all.”
