Good point @PepeParapluie (Edited to add that this was in reference to your first post above. Your second describes how I feel too about using religion as a comparison - it also helps me decide what kind of language I want to use, because I imagine how it might play out if I was challenging the impact of any other belief if it were being enforced as a truth)
And to bring it back to the use of language, imagine a scenario where I wanted to request that a locally organised community event donated its funds to a project other than the church repair funds. I have attended events that were run by a secular and religious collaborative events team which donated funds to the local church (they tend to donate to various different causes), so it's not a far-fetched scenario.
As an atheist, should I stick to the "correct" language of plain fact, rather than using any language from the Christian faith? Would my letter be more persuasive if I did? Obviously, in my atheist world it is a fact that god doesn't exist, rendering any words related to god pointless, so my letter might read something like this:
"Whilst I think it's great that you're raising money for a local cause, I'm disappointed that it's being spent on a building that isn't needed by everyone. The building's purpose seems to be for people to gather together to listen to, sing about and quietly mutter to themselves about a set of life rules, dictated to them by someone who stands at the front and claims that the rules come from a some kind of deity. No proof of such a deity is offered and asking for this is either frowned upon or answered by pointing to words in a book that was first written about 2000 years ago, where nobody knows for certain that the eye-witness accounts of seas parting, water turning into wine, a man rising from the dead after 3 days, a woman giving birth despite being a virgin and so on were seen and experienced exactly as we see written in today's book. Are we even sure we need the building at all when we've got a town hall for community things?"
I've avoided using all of the following words: church, sermon, hymn, prayer, vicar/priest etc, god, bible and miracles. The premise of doing so (in this example) being that I'm taking a hard line, so that I can then go on and suggest what I believe to be a better cause for the funds to be given to. Not only am I avoiding words, but I've chosen to challenge the entire belief head-on as the basis for my argument.
It's hopefully obvious that I would never write such a thing!! There are two reasons: a) I don't need or want to be offensive, just because someone believes something that I don't b) I wouldn't expect too many people who did believe in god (or anyone agnostic) to read any further and listen to any suggestion that followed an opening like that. While I might get a few fellow atheists engaged, if I personally saw a letter that started like that, I would have to make an effort to get to the end and take on board the point being made. IMO there are far better ways to put the same suggestion (an alternative use for the money raised) forward.
So whilst I'm not suggesting language policing the other way round, where people are told they should use words that believers would prefer to hear, I'm an advocate for including the language of belief if it helps your overall message to land more effectively with the audience that you're engaging with. If that involves using words like "trans", so be it. I personally now avoid pronouns altogether on most occasions (although sometimes I use preferred pronouns if the scenario warrants it, but never for a child) and I draw the line at "cis" to describe myself. I don't worry about anyone calling me cis any more than I would worry about a Christian referring to me as someone who might not get in to heaven based on my rejection of god.
(For any Christians reading this whole post, please do know that I would never speak about the church in the way that I did above and I've seen a lot of good in my own community that has been led by the church - plus our local vicar is great!).
