Dan.... you are just wrong here. Of course the word "Yahweh" is used in the Old Testament and other holy books. Those works that will be handled with care and respect. The custom is to not write the name on lesser works that will only be thrown away as garbage. If you write the name, that page now should be treated with reverence and kept.
In a sense it is similar to the way we treat American flags different than other pieces of cloth. Once that cloth is a flag, it shouldn't be thrown in the trash.
It has nothing to do with people who are trying to cuss and sneak it by the censors.
You say I'm wrong, yet do not deal with one substantive point I made.
Try that.
