Like many, you cherry pick verses, even concepts, to suit your particular narrative. Of course Christ said to love all people. By that criteria you seek to imply that there is no behavior that is unacceptable to God. That is patently false. The result of loving people is to share the Gospel, so that they will consider choosing a way of life that is in harmony with God's idea's of the best way to live life. That includes changing sinful behavior. You cannot have it both way's, Claim to be a Christian, and do whatever you want. Christ was perfectly clear, he told the woman who was living with a man outside of marriage, that he forgave her sins because of her faith, but he also said "go and sin no more" after a discussion about her living arrangements. Christ also told the Apostles that they were to share the Gospel, and if it was rejected, to move on. As to your universalist assertion that the same God is involved in all religions, I don't accept it, and neither did Christ, he said " no man comes to the Father except by me "
