Very well said. People do imitate others, especially if a co-worker or someone you know, tells you that their immoral way of doing things is just fine. The other problem facing moral living - and the word morality is still in the dictionary

- is people just shutting up and remaining silent when people openly get in your face and say either, “It’s none of your business how I live.” or “Don’t shove your morality down my throat.”
What? Everybody gets a say and you don’t because the other person knows you’re a Christian and it makes them uncomfortable or because you try to charitably say something like, in the case of cohabitation, “Why don’t you guys just get married?”
That’s part of the problem. We, and the Church, are not supposed to force anybody to do anything. That’s Church teaching. But if we all shut up, especially with people we know/work with, how are we helping to get the truth out? I mean, the Church tells us to tell the truth with charity. How can we be a counterculture to the immorality around us by saying or doing nothing?
Everybody else gets to say, do, promote and even celebrate openly, all kinds of depraved, dysfunctional and deviant forms of behavior as if, suddenly, somebody they heard on the radio or TV or read about has found a new, better way to live, according to them. So some people decide things like: “Why shouldn’t I live with my girlfriend and have sex with her? Nobody’s going to
tell me what to do!” Well - in case you missed it - somebody just did. A total stranger just gave you “permission.”
Peace,
