Supposing this is true, and it seems to just sprout from incredulity, Feser points out characteristics of the first reason that are traditional philosophical definitions of God.
You keep ignoring the basic contradiction (just like you did with the last argument). You are also ignoring the utterly contrived nature of Feser's argument. It really is totally pathetic in its desperation to make this "uncaused cause" fit with an idea of god. For example, he argues it is 'good' because it realizes all of its potential - it has no defects. However, this says nothing about moral good that is ascribed to god.
Just as an example, I could bring the whole thing back to the point I made before, that this "uncaused cause" (in the sense Feser defines it in his argument) is quite clearly the cause of all defects and all moral evil in the world; it is therefore evil or, at the very least, amoral.
Therefore the claim that there is no reason to consider God is, er, unreasonable. You have therefore been indulging in misleading new atheist hyperbole.
Feser's argument is a joke - it provides no reason at all to consider anything like a god (in the usual sense of the word) for the reasons I have pointed out.
Incidently this is always found out when people finally admit they cannot absolutely demonstrate the absence of God.
Just how many times do you need to be told that many atheists (myself included) have
never claimed to be able to demonstrate the absence of god(s)?
However Feser makes the case for at least the classic philosophically described God.
If that is the philosophical case for god, it's pathetic - for the reasons I've given.
What?, hide from science but not philosophy?
Hide form both, it would seem. More importantly perhaps, hide from ordinary, thinking people who have studied neither. Why isn't the important message (morally reprehensible as it is) blindingly obvious to everybody?
