Loli! I agree with you! That’s a first! is a great question. I had never even thought of that, but I don’t think it’s a conscious behavior. We fall into habit patterns when we speak. Sometimes we inherit phrases from the culture around us and I think this may be the case as well. We often say things that don’t make sense or are not exactly the right word. To eliminate racism or sexism or disrespectful phrases from our language takes a lot of energy and focus. it’s almost like learning a new language and it requires a lot of hard brain work.
