Hey , come on guys, there is no reason to be rude. Just because it's something you don't do and something you find silly are you really going to make that big of a deal about it? This is just like if I told you the way you pray looks silly, or the way your face looks when you revere God is rediculous. If this is how they want to show that God is more important than anything on Earth, so much that nothing on Earth is worthy to write His name on, then let them do it. It doesn't cause you to stumble, it doesn't put their or your salvation on the line, and nobody has forced it on you. Just like crossing yourself, it has no real power, it's not to save them, it's a personal sign of respect to their Lord. Are you going to tell them that it's rediculous and silly to show respect to the Lord? When the woman poured expesive perfume on Jesus, and the Apostles were flabberghasted that she didn't sell it to help the poor instead, even Jesus asked them why they wouldn't let her do that for Him. So what wall have you erected in your heart that would make you scoff at people for taking the Lord's name with reverance, respect, and love?
