You know, I'm really cringing reading a lot of these comments on here.
One poster wrote a really fair post about being a Christian, also finding somethings she doesn't agree with, but that she understands it's not her place to police these things, essentially encouraging op to do that same. And immediately, she (sorry, I'm assuming!) is pounced on, being mocked for not liking Jesus on a birthday card. That poster seemed to deliberately be looking for something and totally ignored the entire point of the post.
And so many smug, and 'witty' remarks about how stupid believing in god is.
I'm not particularly religious. I enjoy some parts of the Christian religion. Love a hymn. Enjoy the nativity story. And I believe Jesus was a real man. But that's the end of it really. I can't really believe in a God that allows the level of suffering this world has, how is an all loving god really all loving when they allow babies to be raped? Or children forced to drink filthy water?! Can't.
But I don't think it's ok to just take the piss like so many have. It's just a conversation point. OP isnt setting up a petition to stop use saying Christ on a bike (my personal fave) like many others, she is just voicing an opinion.
I have one very religious friend, as in she attends church, and loves it, apparently. And my son went to a CofE school for a while. So I made an effort to not say those things. It was hard at first, because I am a big user of Oh my god and Christ alive (another fave) but I did it because I like my friend and I understood I didn't have to send him to a Christian school.
Op, if you were my friend, I would always do my best to not use language that makes you feel uncomfortable, as I'd hope you'd do for me. And I think that's all you can really expect. The internet is a cesspit, and we are all going to see things we find distasteful or straight out offensive, we just gotta shake it off.
