This is from carm.org, Christian Apologetics & Research Ministry.
-Apologetics is the 'defense' of Christianity.
Though most of this site hails from the - ‘It’s true because the Bible says so’ - format, this particular part appears to be demonstratively ‘flawless’ in defining aspects of illogic. For what it's worth it's a comprehensive site.
The link below is titled “Logical Fallacies or Fallacies in Argumentation.” There are 18 of them listed here, all Short, simple, and to the point.
If you’re a logic lover like me, or just your run of the mill human breathing, you'll love the idea of being able to describe the very
nature of truth
while you're telling it.
These are eternal gems of logic useful in and for any argument or debate.
