I wouldn't count reverts as converts. In any case, I wonder how many you have turned off of Catholicism by your approach. As I believe you know, I am not a Christian, so the outcome of your efforts in this regard is not my concern. What I am concerned with is encouraging a respectful and fruitful dialogue. To that end, I shall voice my opinion anytime I believe that someone has overstepped the bounds of civility.
Shalom.
