Atheists, tell me, a Roman Catholic: why should I become an atheist?

[Cyberman]

Here's another logical argument which cannot therefore be wrong based on one's private feelings (as opposed to public ones, I suppose?):

1 All elephants are pink
2 Nellie is an elephant
3 Therefore Nellie is pink

Here's another one:

1 Something must be done
2 Here is something
3 Therefore we must do it

And another:

1 God is the most powerful entity in every reality
2 The greatest power is to be able to act while not existing
3 Therefore God doesn't exist

Remember, one's personal feelings cannot refute any of these.
