Well depends on the topic. My assumption is on racism as a whole due to the all lives matter vs blm. I assume each house would concern all races. As you are aware racism isn’t only directed towards one race. I’ve felt it towards myself as an Asian an seen it directed at my friends who are Asian, Hispanic, middle eastern and African American. During and after 9/11, there has been a lot of hate directed at middle eastern people. Racism needs to end and we all can or have endured it. Though racism towards African Americans are well documented in history and the media, people of all color can or have been a victim of it. Hence all houses on fire, and all the fires need to be put out. I mention one house is in worse shape and needs more attention. I believe that is what BLM movement is trying to focus on. There’s been years or hundreds of years of racism towards them and they/we believe it has to end and black lives matter as much as any life.
I must admit, sticking with the analogy, I disagree that all houses are on fire. Maybe one has some flood damage from 20 years ago...one has some foundational cracks from a recent earthquake, one has termites perhaps, one has a lit bag of dog poop on the porch, and one house seems to have a lot fire starting materials inside.
