To answer the OP, I'm English so it's very much a part of my culture to speak mostly in irony almost on a constant basis (noo, really?).
For some reason we love irony (talk about stating the obvious!)
, so I could come off as sarcastic, but usually here sarcasm is meant affectionately (daww ain't that sweet?)
. Though on the internet I try to put it aside because I know people can take it totally the wrong way. However, if I am sarcastic in a non-affectionate way then chances are you're driving my patience (wheew, somebody's cheerful today)
, not by merely thinking differently or having a difference of opinion it's by not listening (pardon?)
, it's by using strawmen, it's by lying, it's by being dishonest, it's by shifting goal posts, it's by condescending, it's by insults, it's by making offensive remarks, it's by getting shirty with me, it's by mistreating other people, it's by being a bigot, it's by over generalising people and making inaccurate assumptions, it's by prejudice. And even then I have a high tolerance, but I'm human so I do have a fuse.
I think sometimes it's worth thinking about how you might come off, I don't know you nor have I engaged you, or at least, I don't think I have.
So I won't make an assumption about the arguments you've made, but I think it's definitely worth thinking if the person is being sarcastic, why are they being sarcastic? Is it because they're generally unpleasant towards religious people? Or is there something you're doing that might be winding them up. I've listed things that would lead to sarcasm from me and sarcasm isn't necessarily a BAD thing, it can be a quick and easy way to put something into perspective - irony can be an excellent use of language for demonstrating a point in a concise way. In the 'catholic priests and paedophilia' comments, if somebody was talking about the 'morality that organised religion brings', I could go into depth about the various immoral acts that have been done by people belonging to an organised religion. Or I could just make an ironic statement to put into an immediate perspective an issue at hand.
I personally wouldn't feel the need to mock religion, the catholic church included, well except for the sake of humour but then my sense of humour will make fun of anything, including atheists and English people. If I were to make a witty comment about Catholics it'd be to make a point relevant to the discussion at hand, I'd try to not insult somebody doing it - I wouldn't imply all
Catholics are kiddy fiddlers, but highlight it as a problem from within the church. My Nan is Catholic and half of my family has a catholic background, if I insult Catholics then I'm insulting my family. If I was a Catholic and believed kiddy fiddling was wrong, I'd be outraged that my church allowed it to happen and not only that but my pope protected them, if somebody made a joke about catholic priests or made a sarcastic remark I'd join in as say, "yes, as a Catholic, I approve".
I've had sarcasm come my way and instead of letting it bother me or allow it to invalidate their argument, it has actually put into perspective what I was getting wrong. I also get it from the religious and a whole lot worse things than sarcasm, I'm sorry but if I'm walking down the street I don't want someone with bible in hand that I'm going to hell if I don't accept Jesus.
