Regarding Ohio State University's "inclusive holiday decorating practices", I appreciate that you have to come up with creative ways to justify your position, one that has a rather nebulous job description, but you should know that Red and Green are not the colors of the Christian Feast of the Incarnation; that would be White. Interestingly, you urge care with the first two colors but "permit" the latter color.
People send me these things for comment and nowadays I just send them to the original author.
Update: Since my response, OSU has removed the document from their website. I doubt that had anything to do with me, but it's an interesting development since this memo has been in place for three years.
