Speaking as an atheist, no, they don't. Generally speaking, Christians just just aren't good enough at arguing their case. Most of them hardly understand any of the tenents of their own religion. The folks on Christian Forums are sometimes better, or sometimes more unbalanced, but even so, as a general matter, atheists know the Christian religion better, and can argue it better.
The problem is that Christianity just doesn't make sense. This isn't necessarily a disadvantage in a religion; there are parts of the Christian religion that Christians are proud of not understanding. God works in mysterious ways, and all that. the problem is with apologists who convince themselves and others that they actually can win all of their arguments and show atheists the error of their ways, and of course they can't.
If I may offer some advice, Christians showing humility, kindness and helpfulness would be way more convincing, and likely to recruit converts, that fans of Josh McDowell and Lee Strobel.
