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

[Cyberman]

I even took the trouble to unpack all the in-quote responses. Please don't do that again.

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

(Argument is flawed there are no pink elephants, haven't seen a real pink elephant on media, zoo.)

Irrelevant - argument from ignorance is not a refutation.

Here's another one:

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

(Argument is flawed as we don't know what that "something" and therefore how can we do it?)

Irrelevant - argument from ignorance is not a refutation.

And another:

1 God is the most powerful entity in every reality

(True)

2 The greatest power is to be able to act while not existing

(Act what? And how not existing?)

Irrelevant - argument from ignorance is not a refutation.

3 Therefore God doesn't exist

(Argument is flawed, therefore God does exist.)

Non-sequitur; and no valid objection raised to the argument, therefore argumemt not shown to be flawed, therefore still stands.

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

(True, but logic can)

Great; you're starting to get it.
