Respectfully, I urge you to recognize your status as a white male and mine as a female when considering our stances on this topic.
Yes, the research study on female undergraduates was one only instance. It does not necessarily translate to all of the female population.
But again, as per my article, even performing a quick Google search will reveal that “girl” has been recognized publicly, on a mainstream level, as problematic as a term for some time now.
For instance - https://www.theguardian.com/commentisfree/2014/may/27/is-the-word-girl-offensive
Also notably, look at the definition of girl in dictionary.com - it is not just simply synonymous with “woman” and is not free of its offensive connotations.

I encourage you to work on being mindful. At this point, it seems you’re being particularly antagonistic toward me, which I hope you recognizes actually hurts your argument and doesn’t serve your point.
