As far as me judging you, I don't judge anybody. I am however required to judge sin. Your sin seems to be pride more than the tattoo. The tattoo is just a symptom. We have a Saviour that heals the "tattoo" parts of our lives, but you have to repent and tell God He's right and you are wrong. Otherwise, it's not repentance. You will not be judged by me, that's true, but when you come before God and He wants to know why you were presented with His Law on FR, but attacked the poster, instead of contemplating His Law, He may wonder just how much you have submitted to the sovereignty of God. The Word of God judges you, not any person. When you are confronted with the Truth and reject it, that is willful sin and requires repentance. If God can forgive people on death row, He is sure to forgive pride. But you must agree with Him first to be serious. I have counseled women that have had abortions and finally realized their error. God is quick to forgive, but the women wouldn't forgive themselves so easily. Jesus said He didn't come to change the Law, He came to fulfill it. NO LAW HAS CHANGED from the Old Testament. Jesus has just paid the price for our breaking of the Law. When people say the Old Testament doesn't count anymore, they are saying Jesus died for nothing because the Law doesn't matter.
The poster was just asking about tattoo's and now he knows what God thinks of them. No one was judging you. You are judging yourself. If you want to conform to God's Will, then get the tattoo removed and repent. If you get a chance to preach again, you might use the opportunity to bring this up. Another topic to explore is the excessive wearing of makeup, jewelry, revealing clothes, etc, because of vanity. I'll let you look up the verses.
