"Long time, no see" is now considered "offensive, non-inclusive language" at Colorado State University. Administrators there (and I use the term loosely) have decided that the greeting is derogatory to people of Asian descent. Eating dogs is still perfectly acceptable; it'd be unsurprising to see dog on the campus menu fairly soon.
Leibee also noted that administrators discouraged use of "you guys" in favor of "y'all," which is gender neutral (and ungrammatical, but this is apparently less of a concern). Her column does not claim that administrators force students to use the gender neutral terminology, just that such terminology is preferred.
Isn't "y'all" sort of "cultural appropriation"? Just askin'.
Reckon that's okay with the "administrators" there, though.
