Only God can judge the actions of homosexuals ie sodomy and gays will be judged by God. Just like Sodom and Gamora was judged.
This is where Christians have made a grave mistake. God absolutely calls us to judge! Our judgment is to be a righteous judgment though! A Christian has the law of nature and the Federal Government on his side right now. Just go to the Centers for Disease Control and it will tell you everything you need to know about sodomy. The CDC labels it as "Men having Sex with Men" - because they cannot use any "negative" terminology associated with the Bible or Torah.
This is the time for Christians to not back down and say "gay is ok." Sodomy is deadly and full of disease. This is a truth that cannot be denied. Don't buy in to the lie that Christians are not to judge. That is a lie straight out of the pits of hell! Pro-sodomy Christians have poisoned the doctrine of Christ. The Christ of the Bible taught from the Law! He absolutely taught that sodomy was an abomination before the eyes of God. Christ said I came not to destroy the law but to fulfill the law! That is a Hebraism of the time. To destroy the law meant you were misinterpreting it. To fulfill the law meant you were interpreting it correctly. This doesn't mean you have to get in peoples faces and tell them they are going straight to hell however it does mean that when you are in the company of those who are spreading the false lies that gay is ok you need to speak up with the truth.
When I meant judge I mean that that includes administering punishment, ie, Sodom and Gomorrah. Only God can punish sinners.
And I believe that your definition of judge only includes our not accepting or refusing to follow something or even defying something that is a sin of which I completely agree.
