Ybe an atheist

[Abaddon_ire]

An opinion is something that someone believes to be true:

Sure. What of it?

" there is no evidence for belief in a deity,"

Wrong. There is no evidence for any deity at all. This is not a matter of opinion. It is a matter of fact.

" which is supremely logical".

Wrong. Absent any evidence, why, logically speaking, would you accept any damn fool idea? There is no evidence for unicorns, dragons or talking donkeys either. Is it reasonable to assume those exist too? Simply by having no evidence?

"  No evidence = no belief"

Bingo, you eventually got something right.

A fact is something that is true:

Sure.

1. If As had  logically supported reasonable reasons, then they would give them

We do, we gave them, you promptly ignored them.

2. they admit they are opinions or have trouble seeing that they are

Lie. Why must you lie?

C. As have no logically supported reasonable reasons

Oh. You are innumerate on top of anything else. Frankly, anyone who counts 1...2...C needs their head examined. Seriously, you find it a challenge to count to three? Really?

Def. No E = Unbelief
If there is no E then U  (nice premise could be the start of a "supremely logical" argument or not)

Define "E". Then explain which orifice you pulled the term "supreme logic" out of. Nobody used any such term until you invented it out of whole cloth.
