It takes a special grace from God for novus ordo-ites to convert because
1) they don't want to believe they've been duped,
2) the "conservative" ones think THEY are the ones fighting for the Faith (being "under Rome" and fighting is the right course)
3) they think trads have "abandoned" the faith but it's just an excuse to avoid them so their conscience doesn't bother them
I've tried many, many times to have conversations with novus ordo-ites (and this includes family members who were born and bred in the TLM but left for the indult) and i've had 0% success (that I can see). I'm sure it helped to get them to think, but visibly, I didn't see any difference. Only God knows.
However, if you want to get anywhere (or have a hope to), I suggest the following, for your sanity's sake:
1. Keep the discussion on a factual basis, concentrating on V2, the new mass changes, etc.
2. Don't start talking about personal sanctity, or the good things certain bishops and priests are doing. It's irrelevant. Only God knows who goes to heaven or hell. It doesn't change the fact that objectively, V2 and the new mass are wrong, and far more people are being led astray by it, than helped by it (or in spite of it).
3. Give yourself a time limit to decide the good will of the people you talk with. If they don't show good will, move on. Your time is better spent on charity/prayer than trying to convert those who don't want to.
May God bless your work; He will certainly bless your intentions!
