As a spiritual person who believes in Jesus Christ, I, personally, don't use the expressions "goddamn," "Oh, Christ," or "for Christ's sake!" I don't use them in casual conversation or even in my writing when I'm creating my own characters and the way they speak. I just don't. I feel more uncomfortable saying those expressions than I do swearing or even saying "Oh, God!"
However, The Boys in the Band is one of my absolute FAVORITE movies of all time in Queer Cinema, and "goddamn" and "Christ" are plastered throughout almost every line of dialogue in that movie. And I have no problem with it. I wouldn't want anyone to bleep or mute it out because I think the dialogue Mart Crowley wrote is absolutely genius and shouldn't be fucked with.
I know that it has no bearing on my spiritual beliefs at all.
Did you ever think that you're part of the problem? You're encouraging the shame and dehumanization by essentially saying "this is how you're supposed to feel every time you hear that word!" Instead of saying "every time someone uses the word in this way, they're the ones who are ignorant," you're saying "every time someone uses the word this way, you should feel bad about yourself, and if you don't, you're part of the problem."
That's such a fuckin mixed message, trying to attach pride and shame to one word at the same time.
