Why? Sometimes people need to be reminded that their brand of Christianity is not shared by all Christians. That even Christians have different philosophies from other Christians. Why should you be incredulous that a Christian has different view than you? It's called Christianity, after Jesus Christ, not Nadiineity, after you.
Yes, GOD. Not you. Really, it's none of your business. Christianity, remember... Not Nadiineity. Your approval not needed or required.
And by the way, God isn't a dog you sick on people who do things you don't like... So making an assumption about what somebody is saying, then threatening to send God on somebody because you don't like the conclusion you jumped to is not Christian. It might be consistent with Nadiineity, but not Christianity.
Christianity already has a martyr. No need to make yourself one because you feel nobody lives up to the standard you feel they should. Again, maybe you're the Nadiinety martyr, but in terms of Christianity, placing yourself on the cross... Not needed. So knock it off. It's pretty selfish and high-handed of you to assume that people who have premarital sex don't care about God. If they do or not you don't know... It's something you're totally ignorant of. So acting like God calls you every night and says "Have you heard about Tropi? Oh my Me, she had premarital sex 4 years ago... She like totally hates me, I just know it. She like totally just doesn't get me, or whatever. You should totally talk to her." is unnecessary, and it elevates you to a level of self-importance you don't really need or deserve since, after all, you're a sinner like the rest of us, inspite of your attempts to get us to believe otherwise.
