Why do people argue whether or not we are similar to simians?

I learned a new term the other day. "Chimping". It refers to the action of someone who is looking down at their digital device, trying to figure out how to use it. The term came from the fact that, well, you look like a chimp would when doing the same thing. Here is a picture of my dad and me both simultaneously Chimping at a family dinner. So FYI, it appears to be hereditary!
