Cognitive dissonance works better than ridicule. Nobody is going to win converts by desecrating the Eucharist, or by ridiculing believers as incompetent. Back when I was a believer, that is what kept me from converting.
Where were the arguments, contradictions then? Did my fellow unbelievers even know such arguments existed? All they focused on was to ridicule and belittle my self-esteem which was already at rock bottom levels, thanks to guilt from sin.
Now I am saved into the holy unbelief, and I find my fellow men doing the same lame strategy. No wonder why it took Dawkins et al, to bring unbelieving population back to normal levels.
