There are evil people in the world who prowl the Internet or emails searching for certain key words. These people may target those who use such words in a way that is, for whatever reason, deemed offensive. This is why several missionaries I know don't spell out certain words in emails and online. Why attract extra attention from people who wish to do you harm or get you kicked out of your country?
I suppose there are evil people who, if they felt offended by something said here, might search out members they could identify and track them down via their signatures on the board. The risk of that seems low in the West, but there are members on this board who live all over the world, so I don't blame those who're trying to be extra careful for the benefit of us all. I don't personally worry much about it. It comes with the territory of being upfront about one's faith in Jesus. Then again, I live in (relatively) safe Colorado.
