Seems to me that using G_d or G-d would cause more confusion that honor since not all people are educated about the traditions of different religions. Fluther is the first time I’ve ever seen people do this. I always thought that people were just afraid to say His name or a filter was blocking the word.
Now, being a Christian, I understand the use of His/Him and that could in turn be confusing to someone who wasn’t familiar with Christianity. But if someone were to take it in context, they could easily figure that out. If the conversation is about God, then I would expect “God” to be somewhere in the document/conversation before I saw “Him” or “His”.
I mean no disrespect for the answers given or to any religion…I just wanted to present a different perspective.
