My daughter, a teenager, was vocalising the BLM viewpoint the other day. When I said ALL lives matter I was told I had no idea what it was like. Maybe - but I'll stand by the view that all people are equal and should be afforded the same level of rights and respect, up until the point they step outside what a reasonable human being would be expected to do. My response would then depend on both their and my situation at the time, from ignoring to physical intervention.
