Christianity is fine with me. Fundamentalism isn't.
And having Rey alone, virginal and choosing a nun like existence is fundamental, whichever way you look at it.
I understand that view but there's no way that was intentional on the part of the films. The problem from the beginning was Rey was given no personality or any values, which frankly has come about because those writing films in Hollywood are at this point in time writing female characters as blank slates under the misguided idea that makes her stronger. Having female leads is not an issue, but if she has no female perspective, aspirations, desires or just any feminine aspects about her, then she's not really a character. You look at someone like Wonder Woman who was the epitome of femininity and all its strength, you've got a compassionate, romantic, beautiful and elegant goddess who also kicks arse in 6 inch heels.
Switch to Star Wars and you've got Rey who has been given no real personality, no real goals or values, who's been dressed in a bland and unfeminine way, and who's not been allowed to find love. Oh, but here's some badass piloting and sword skills to make up for it. The best women heroes have all come from a woman's perspective in their quest, Leia, Ripley, Sarah Conner, Katniss Everdeen, The Bride, Eowyn, Furiosa, Wonder Woman, bad place I'd say even Padme and Jyn Erso could be included, the list goes on. That view you have is a result of creative minds who think in order for women heroes to have power they have to act in any way other than what a woman would. And frankly no-one wants to watch that.
