I swear in certain contexts, especially when I'm using a computer, and I find this statement utterly ridiculous. There are many reasons why people might prefer not to swear - how you were brought up; because you think it exhibits a certain sense of self-control; because you take delight in using circumlocutory expressions which avoid swearing (I'd be more interested, frankly, in a speaker who says "unmitigated bunkum" than one who says "bullshit"); because you work in a context in which swearing is inappropriate... To say that all of those reasons make people "priggish" or, worse, untrustworthy is just very silly.
