normalized sins in Islam

I just want to talk about couples being normalized in Islam and it's becoming more and more common nowadays, even some of them dating non muslims and some breaking up with their partner since it's Ramadhan but would get back together afterwards

A few days ago I posted a post on my country's reddit channel about it, since it's Ramadhan I just wanted to give advice and maybe make them realize it's wrong and I did it respectfully yet somehow I get comments saying I'm trying to control them, saying I should mind my own business and I have my own sins to worry about

Of course everyone has sins and I just wanted to give a friendly advice 😞 honestly I'm kinda disappointed in it ,even some saying "It feels good to make sins" "you're just mad because you're single"

What do you think about it,did I do the right thing on giving the advice?
