I never encourage people that have left, or that are showing signs of weakness in the religion, only because I believe in having free will.
I just continue to be polite to everyone equally whenever I encounter them in my everyday life doings. Even to the disfellowshipped ones have I never denied a smile or a good morning, as it's just the right way to treat a person.
Hey, ultimately, we all face the consequences to our actions.
Be well.
