CMV: Black Lives Matter vs All Lives Matter

First, I definitely support the BLM movement and I'm honestly horrified at the inequality that black people are facing right now. But...

I have no idea why saying "All lives matter" is a bad thing. How am I being racist for trying to support all groups facing inequality instead of just one? I'm bisexual and hispanic, but if I say all lives matter (or even hispanic lives matter) I'll get labelled as racist even though I'm literally supporting ALL lives.

Somebody attempted to explain it like this: "If one house is on fire, you don't put water on all the normal houses around it, you put water on the one that's burning." This is a horrible explanation, because it's pretending that no other groups of people are facing inequality. Within that analogy, almost every house would be on fire. Maybe one fire is larger than all the others, but you can't just ignore the other fires.

I feel like a total asshole for believing this, but I just don't understand how supporting every group is worse than only supporting one.

ALM didn't start as a movement to make sure equality was brought to everybody. It was started to tell BLM that they're not important in the context of All Lives.

So while you're correct "all lives DO matter". The actual ALM movement was started to silence BLM.

That's the difference.
