Yes, of course you can (and you definitely should in your personal life) disregard all the cultural context and baggage that has largely been attached to Christmas and Santa and just celebrate a time of vacation, family, love and giving… but imho the chart assumes to represent a cultural understanding of figures from story and myth that have significant symbolical value in modern, americanized, western culture and to represent the cultural context of those symbols.

So to disregard the cultural context in a chart that tries to show cultural context is… bold.
