If I may add, if there were to be a large event that was well advertised, I believe unknowing Jews would come.
Jews who do not know about Torah Judaism, when among religious Jews, will have tremendous respect and a lot of questions.
You may find them to be very accomplished/educated, good-natured, spiritual, thoughtful, and sincere. They just dont know about Torah, the Gedolim, and the Hashkafa of things.
Being mekariv someone is a very slow process of up and down and lateral movement. Like I heard someone once say, balei tshuva are expected to change almost everything about who they are and how they live and who they associate with. It is a big thing. Mitzvos cannot just be presented like a laundry list of “good deeds” with the approach that if you want to be a good person, just do all these things; the more the better.
Hatzlacha rabbah to all who try to add a little light to our brothers and sisters who just dont know, through no fault of their own.
