I use them when warranted, which isn’t very often. I don’t think the avoidance of using swears is a religious thing, it’s a language/cultural thing. For some reason they’re just deemed “bad words”. They exist in almost all languages and cultures as far as I know.

A good friend of mine swears a lot unless kids are around. I don’t mind it, but he’s sort of “that guy” because of it. If he was someone I just met, I’d think he’s just a bit lowbrow and that’s about it. I wouldn’t think poorly of anyone because of it as long as their attitude is good.
