Can you persuade me from Agnostic to Atheist?

[wiploc]

Can anyone here persuade or convert me from being agnostic to being atheist?

I'll try to talk you from weak atheist to strong atheist (from one who doesn't believe either way to one who believes that gods do not exist).

Is that a fair understanding of what you're after? 

I can talk about, for instance,

• Why we know the standard Christian god doesn't exist,
  
• Why any particular theist argument (not including the thing about polonium halos) is garbage,
  
• Why gods generally are tremendously unlikely, or
  
• Why it's fair to believe that theists don't have any reasonable arguments. 
  

But I don't want to write a book.  I need feedback from you. 

Is one of those points above what you're after?  Are there any specific theist arguments that you have trouble refuting?  Where would you like me to start?
