Look dude, what you're saying is great, but all lives matter is a real movement made to make white people feel tragic and opressed, so associating yourself with it is a bad idea. It's a completly racist movement, and I'd like you to be aware of this before you start saying "all lives matter," everywhere, because people will assume you are a racist or an enabler. Again, your message is great, but it can easily be taken the wrong way, especially right now.
