I know lots of non religious women who don’t stand up to their husbands or male relatives.
I think we have to be very careful with statements like this.
Firstly, (apart from Christian/catholic religion), there is not one religion worse than the other for child abuse.
Someone being an atheist isn’t automatically safer than a Christian or Muslim.
Secondly, it implies that women in non religious relationships should be able to stand up to their husbands and it blames the victim for not doing something just because she’s not religious.
