Avoid using words, images, or situations that reinforce racial, ethnic, or religious stereotypes (even stereotypes that may appear to be positive). Cultural appropriation is not appropriate.
Unless there's a specific reason to, avoid referring to individuals by their culture, ethnicity or background.
Avoid terms that identify people from a specific perspective. Don't use "non-white", "non-European", or other terms that treat whiteness as a default:
Ethnicity refers to the sense of identify which comes from shared cultural characteristics such as language, religion, history or geographical location. Don't use it to describe someone’s racial origin.
Above all, don’t make assumptions: ask how people identify themselves, and be aware of complexities within racial, ethnic, and religious identities. For example, not all Arabs are Muslim, and many nationalities and ethnicities include various religious practices and traditions.
