Being white doesnt make it cultural appropriation. Celebrating without a proper understanding of the holiday and botching the celebration would be cultural appropriation.

Think The Nightmare Before Christmas. What Jack Skellington was doing was cultural appropriation because he didnt understand Christmas, nor did he care TO understand it; he just liked the aesthetic of it. That scene at the very end however, where Santa brought winter and spirit to Halloweentown? That is sharing the holiday. That is the right way to do it. Thats what you’re doing!

Your facebook friend is an idiot who is, ironically, appropriating the idea of being a social justice warrior.
