The big one here is the use of the R word. We work hard to educate people to understand why it’s hurtful. This link is an excellent resource on how to have that conversation. https://www.r-word.org/r-word-dialog-1.aspx
No matter the topic, stay calm and respectful. When we take the time to tell someone what they are saying is offensive it can embarrass them, and they feel a bit defensive. So much of the time there was no malicious intent. Educate whenever you can, at first it may feel difficult and even easier to just walk away. You can do it! Take a deep breath and remember who you’re advocating for.
