AITJ for not being religious enough before being named the godmother to my husbands nieces new daughter

For context I am not religious in any religion and last year before my husband, our kids and I went to see his family in Scotland, his niece asked me would I be the godmother to her new daughter and I said I’d be honored to and she respects I’m not religious. During our visit we go to the church to meet with the priest two days before the baptism and when the priest asked me what I know of the religion I said, “I don’t know much I’m not a part of the religion.” The priest then pulls the niece aside and the next thing I hear is her saying, “Does it even matter? She and my uncle live in USA, we’re here in Scotland! They visit when they visit.”

The priest then tells me either I get baptized to be named godmother or don’t show my face at the baptism. Before I can tell the priest a few choice words my niece steps up and says, “I’m not going to force her to be baptized before the baptism of my daughter! You’re being unreasonable!” The priest says either a new godmother be picked or the baby doesn’t get baptized. My niece stood her ground and the priest then kicks my niece out of the church.

All other Catholic Churches get word of my niece and forbid us to enter all because I’m not allowed in due to not being baptized and because my niece won’t pick someone else to be godmother. AITJ for not being religious to be godmother?
