It's taught that the name of the Abrahamic God is powerful and should be revered, so it's best not to write the full name down. Hebrew also doesn't contain any vowels like English has, so G-d would be similar just covered to Latin script and the English language.

Your unfounded and irrational hatred for an entire group of regular people who happen to worship a different version of the same historical God (worship of Yahweh starting with Abraham) is morally reprehensible, and about as logical as hating everyone with green eyes. Your zealotry for Christianity blinds you to the realities that not everyone believes the same as you to the point you think everyone not Christian is demonic (lunacy), and it is not your duty or right to look down on people who are different than your specific point of view. Your simplistic world view is reflected through your blind hatred of the Other. The hatred that fills your heart is despised by God (well, maybe not God as you see him, in which case I don't want anything to do with your version), as well as decent humans all over the world. Not to mention the basic fact that hate breeds hate, and having such hate in your heart, let alone being proud of such hate, poisons the soul. I hope your God takes up that issue with you when, and if, you ever meet them.
