Daas Yochid, if someone does not want to be modeh al ha
emes, he will not. Pharoh is the primary example.
My point about the Chilul HaShem was that it is Chilul HaShem to squeeze money out of unwilling and protesting people to support oneself in learning. If the raya from Yevamos is not a raya for you, I have nothing to tell you anymore.
Btw, chevrah, I hold that the Earth is flat! Anybody wants to prove me wrong?
