17 He said to His disciples, “It is inevitable that stumbling blocks come, but woe to him through whom they come! 2 It would be better for him if a millstone were hung around his neck and he were thrown into the sea, than that he would cause one of these little ones to stumble. 3 Be on your guard! If your brother sins, rebuke him; and if he repent ...[text shortened]... here would rebuke a fellow Christian due to sexual immorality?
Jesus instructs you to do so.
There is some truth to this.
The thing is... "rebuke" is a bit strong of a word. You should let people know that they are in the wrong but the idea that I can bear over them and force them into some position against their will is wrong. Our tradition believes that we can make deviations from canonical law to aid people in their journey to God.
Let's not rebuke people over whom we have no authority!
A father has every right to scold his daughter or his son. A grandparent has some right to give a lighter scolding to his grandchildren.
But, who am I? If you are not my child I can only speak to you as a "fellow human." And if you do not accept the premise of God, and you are not a Christian, what can I say to you at all?
"Follow my religious beliefs, even though you reject them...?" That is hardly persuasive. For many, we have to start on a more basic level.
Some people are fortunate to grow up in good homes that know Christ. Others are in homes where Christ's name is spoken much, but none of it is to the credit of Christ and the edification of the listener. Others, still, have circumstances even more distant from Christ.
Let's not rebuke people we don't know. I won't interfere with someone disciplining their kid or angered at their best friend or someone they have some deep relationship with and whom they are heavily invested in. That is their own business.
But for everyone else... we need to not judge them, and to be merciful, and to be understanding, and work to convince them of the right path to take...
And, needless to say, while that is very liberal, let me be very conservative for a second: and we must never equivocate or backdown from the truth that you point out that sexual immorality is very bad.
