Why do some theists keep asking questions about atheism and some block atheists or get mad when atheists try to answer those questions?

"But I tell you that everyone will have to give account on the day of judgment for every empty word they have spoken" (Matthew 12:36).

That probably happens both ways. It is just people trying to push their views and stifle disagreement. It seems rather pitiable to me.

Why do theists denigrate atheists and then block from answering?   

These theists have no confidence in their faith. 

They must realize just how silly their delusions are to sane people!  They suffer from "Secular Phobia". the fear that their God may not exist!

Great - christian sinner sitting here, judging other people while sitting with a hardon up his backdoor.  That's awesome.

Great question if you didn't ask it 23 times :)

I agree. It sounds like something an atheist would do. With the anonymous feature, it could be an atheist doing it. Though I don't believe it's atheists doing it all the time. 

You seem to be off your meds today (or, on something else...)

Theists fear the truth.
