The first two links that came up in brave search are:
https://thearc.org/blog/the-truth-about-the-rword/ and https://www.specialolympics.org/spread-the-word/our-words/the-effects-of-the-r-word
These two pieces read very much like propaganda. They don’t source any scientific data, resorting only to your emotional response. I might tone it down, if thy linked a scientific paper confirming this issue, published in well respected journal. But it looks like these two articles either didn’t bother, or in worst case scenario avoided actual data on purpose.
