I'm glad that you realise that non-muslims can't be convinced through illogical emotional outbursts and pothawari one-liners. The fact that the vast majority of our ulemah have befallen to this level doesn't alter the harsh reality of vast intellegensia that is swarming around you.
What you need to remember, is that until you have the knowledge and nous to try and tackle these type of people, then the general rule of thumb is 'if you can't convince them, then confuse them'. Just continue to act like a complete charlatan and waffle on like you know what you're talking about, they'll soon get bored and the tacit understanding that you're not for turning.
I'm also glad that you've realsied your grave lack of faith and belief, maybe it will act as an impetus to try and realise God through thought and discard the song singing mullahs.
