Sure, absolutely. If you have, say, a "Black Lives Matter" sign and also a "Fight Back Against Sexual Assault" sign (or whatever other cause), then no one will be mad, those are both great causes to support.  

But at this point, All Lives Matter as a slogan is extremely associated with people responding to Black Lives Matter with it, by showing up to BLM events with All Lives Matter signs, so that is going to be what people think when they see it. Especially since it isn't really about anything else in particular, it's gonna just sound like the point is "stop talking so much about Black lives"

Got it, so the issue is that the term is politicized and has a deeper meaning of saying that black lives don't matter as much?
