Yeah, it's specifically the not talking to a kid version that bothers me.
I pick up a subtext of self-importance and I think that's what I find irksome. A mom is a parent. A momma is a special parent who will do anything for their baby, you'd better watch out. A kid is a child. A kiddo is a specific child who has a close bond with their momma or teacher that you wouldn't understand. That's the vibe I get.
I'm not one of the people who downvoted you. I like your passion. But maybe this is one of those things we can deal with after we've got a handle on climate change.
