it's the wrong way to conceptualize it.
what if i were to ask you why you don't celebrate lemuria?
here:
https://en.wikipedia.org/wiki/Lemuria_%28festival%29
so, why don't you celebrate lemuria? if you don't celebrate lemuria, you must hate lemuria, right? you must be anti-lemuria!
it's absurd. i don't celebrate christmas because i consider christianity to be medieval, and it's adherents to be primitives. i live in a modern, secular society and i simply don't have time for your dark age nonsense.
