Health, I think it is incumbent upon everyone to be mekarev rechokim. And if you don’t know how, there are people and orgs from who to learn. And if you are afraid of the hashpo’oh of the not frum on your family instead of yours on them, you are saying to your parents and to the gedolim of the last 60 years that all of the mosdos and chinuch they built up were a waste of time and money.
I think kiruv is the truest expression of veohavto loreacho komocho – and on that mitzvah there is no condition of ehrlichkeit on the part of the person you demonstrate ahavas chinom to. And I would direct you to the message of the famous story of R’ Shmuel Shmelke Horowitz M’nikolsburg (brother of my gggggg grandfather) and how he helped Hamelech Menashe – the epitome of rishus – enter Olom Haboh. Our responsibility to love and engage and foster the observance of even one mitzvah is constant and unending.
