I admire your conviction and belief. Don't get me wrong it's just that some times people have doubts and they are trying to clear them but cannot state them as clearly as they would like to.
Please try to grab every opportunity and invite all those for a discussion, you will be surprised how willing people are.
One of my teachers once said, and it stuck "Doubt yourself 70 times before doubting some one else"
(Here go the mqm members on a roll now, but I have already doubted myself more than 70 times about Altaf Hussain. Momin aik soraakh say do bar naheen dasa jata.)
