"Atheists are tough to beat though, I will admit."
More like trying to beat a Predator (i.e. a 'Yautja' armed with a cloaking device, wrist blades, cutting disc/glaive, and plasma bolt launcher) with a water pistol.
"Since this is an atheist world"
Oh, if only...!
"it's easy for an atheist to win a debate over a Christian because he has a lot more sources."
And something called facts. As opposed to fairytales and bullshit found in a book of lies.
"But if you choose your gameplan correctly, you can easily take them down."
I've yet to see any fundie try and convert Richard Dawkins (certainly the likes of yours truly!). And if the likes of Jonathan Edwards - a long-time born-again Christian - can become an Atheist by dint of his own logical and critical thinking efforts, then even the supposedly impenetrable walls of 'faith' & 'belief' of a fundie like those on Ruptured Retards can be destroyed.
I've seen what happens to a fundie who's made to realise that everything they've been taught to 'believe' was a lie - and it's not a pretty sight. But it's possible.
And if a black man can become the most powerful person on the planet, then, frankly, nothing's impossible.
