@cybermanleader "Saying 'All Lives Matter' right now is like saying 'Save All Forests' in response to someone saying 'Save The Amazon'."
"That's like saying 'all houses matter' when your neighbour's house is on fire." (You could even link this example to the Australian bushfires, which garnered worldwide attention. No one was calling to pay attention to other disasters at that time! The Instagram video below demonstrates this beautifully and is worth sharing to further your point.)
"Saying 'All Lives Matter' is like going to a cancer fundraiser and saying 'There are other diseases, too!'. Yes, every life matters, but Black lives are being disproportionately impacted and killed because of racism, and that's why Black Lives Matter is so important."
