The tone here is terrible, but I . . . don't think there's anything wrong with not inviting people who don't follow your faith to your religious events? I am Jewish, my partner is not; by mutual consent I don't bring him to my family's Seder, because he would be incredibly uncomfortable being expected to join in prayers he didn't believe in, and our Seder is not a secular event. If LW wants to have a religious Eastern meal, LW should knock themselves out, and get together with atheist relatives on different occasions.
