So, the evangelical circle of people I mentioned in the f-locked post below do a lot of things together, and I am starting to be invited to these things (not as a conversion attempt, just as a social event). Which, hey, fun. But at these events, there is discussion of religious matters and beliefs that my liberal, Catholic self and my conservative, evangelical compadres disagree on. I'm sketching out a new set of rules for myself about which things aren't worth engaging with and which things are worth speaking up about (well, I have one already for social gatherings with evangelicals, but it requires some adapting for members of this particular church - not because they're worse people, but because they have some beliefs I've not encountered before), and adapting it as I go along.
So what I wondered was: what are your rules for this kind of thing, and where do you draw the line between letting it go and confronting it when it comes to things you find objectionable?
For myself, I usually lean towards letting it go, on the grounds that the purpose of social events is not to prove who's right but to be good to each other and enjoy the company. There are many occasions when I've felt like jumping in to correct a few things, especially if they're statements like "Christians believe [insert belief specific to evangelical Protestants]", but I won't do so if it's only going to come off as confrontational ("and as a Christian, I believe that sola scriptura is a Protestant heresy!"), which is, well, most of the time. But on the other hand, there are some things I really don't want to stay quiet about, and don't think should be allowed to pass without comment. "Gay people are more concerned with their own pleasure than with what God wants", for example, deserves some sort of rejoinder, especially when the person saying it is assuming you agree with them, and I once caused a very awkward pause at somebody else's party by disagreeing rather firmly with that one. So, where do you all draw the line between 'not causing awkward silences at the dinner table' and 'not letting offensive material go unchallenged'?
(Tangentially, also, I don't think the people in this particular circle know what I believe. Some of them assume I'm one of them, and some of them class me as non-religious. Their church has a very poor opinion of liberal Christians and of Catholics, so possibly this is for the best, but... there'll have to be a point at which I mention it, sooner or later. Wonder how well that's going to go down?)
