For most women in the UK, of all the religions it is Christianity that has had the most misogynistic impact on their lives. E.g. the culture around unmarried mothers was absolutely brutal before the 60s and not great after, still isn’t fair. And that is largely down to Christian morality shaping social attitudes. Rape in marriage not being criminal until the 90s was down to Christian attitudes to women. The history of denying women education and leadership positions and appropriate careers that we have still not fully overcome - down to Christian attitudes to women’s “place”. And less explosive but more all encompassing things like the attitudes what women wear, Etc. all shaped by the Christian Church.
All of this has affected me. From the impact on my grandmother of being illegitimate, to the abysmal situation my mother was in as a single mother in the 70s and 80s. The school curriculum, and uniform. Sexist expectations about what we should do in Church, Guides, School, etc. Career availability. Attitudes to sexuality. And on. It’s only really the last few decades that it has become not okay for people to say “Well it’s not very Christian” to back up sexist social pressure. And there;s still some pressure there, it’s just no longer as popular with the majority.
And the Chruches themselves have not become bastions of equality. The Catholic Church is still chockingly sexist. The Church of England is finally allowing women an almost equal opportunity at leadership, but they are committed to TWAW, so still plenty of misogyny there. The Churches that don’t have great hierarchies have tended not to have such obvious stands against women’s equality, but they still tend to have a fair number of social attitudes that are pretty sexist.
So when people say - “look at the awful, sexist Muslims”, those of us who say “Hold a minute, they are people like Christians.” aren’t necessarily thinking “No, they’re wonderful!” (I’m certainly not). We’re just giving you the side eye thinking, “Right, cause Christians are so great. </sarcasm>”
