I’m not going to engage with the original post because I don’t want to derail things and because the underlying politics are not something I have context for, but can we please retire the exhausting notion that holidays with an explicitly and overtly religious origin — especially a religion like xtianity that’s been so aggressively proselytic — are secular?
I’m sorry. You may choose to celebrate them from a secular standpoint, but their existence is part of xtian hegemony and cultural dominance. Everyone’s personal experience is different, but there are so many people in minority groups who have felt pressured to join in these supposedly-secular celebrations or had our lack of celebrating them weaponised against us that it’s important to acknowledge where they actually came from and why treating them as secular (and therefore othering — or worse! — those who don’t want to engage) is inherently problematic.
