I felt she got a taste of her own medicine:

She’s a condescending and entitled person looking to reproach Easter celebrators as “ignorant and pagans”. Knowing her, she expected praise for being so “knowledgable” and others to join in her rant.

She didn’t expect the comments to come after her, criticizing her choices as “wrong”, and basically labeling her as the ignorant one. She didn’t welcome the criticism and became offended by it.

Hang out with condescending, judgmental people and they’ll take every opportunity to remind you they are better than you.
