Why is it that anyone who even questions the assertion that the Earth is flat, gets insulted and gets a thumbs down? In fact my belief in a global or spherical Earth is because it has been proven by the science not any 'NASA worship.'

Well, I didn't thumb you down, but I did call you out for your confirmation bias, and it's precisely what Dr. Sungenis was guilty of as well.  You see the word "sphere" or "globe" and automatically just read into it your own prior bias, that "aha! this must be a reference to ball earth".  That's where I said you're retarded by NASA and mainstream science, where your intellectual perspective on the matter has lost objectivity due to your "a priori" adherence to the conventional science.

Sungenis did that constantly.  "Aha! Look.  Church Father says 'sphere'" ... and even in one case he jumped on a mention of "circle".  But if you read the rest of those Fathers, they're clearly talking about she spherical shape of the FIRMAMENT and not the ground we walk on.

Nowhere is this more evident than when Sungenis put on the cover of his book the DaVinci "Salvator Mundi", because Our Lord is depicted as holding a "globe".  Well, look closely, but the "globe" contains both a (flat) earth surface AND the sky with stars in it ... all within said "globe".

So it's absolutely the case that you are unable to objectively look at evidence because you're injecting your prior bias into things, engaging in "eisegesis" as Sungenis refers to it, and that's what is meant by your mind being retarded, aka restrained by your bias.

I'm willing to accept that some Fathers believe the earth was a ball, and for a while I simply accepted the contention that the Fathers did mostly believe in earth globe ... until I actually looked into what they said and realized it was just a pack of lies from people imposing their bias onto it.

Similarly, on other issues, like Baptism of Desire ... you'll regularly find this mendacious contention that the Church Fathers unanimously believed in it.  But if you look, it's just a lie or else a fantasy created by their own bias and wishful thinking, thereby retarding their minds from an actual objective perspective on the evidence.  If you actually look, 7-8 Church Fathers EXPLICITLY reject BoD, St. Ambrose was making a distinction between "washing and crowning", saying that BoD types cannot be "crowned" (aka enter the Kingdom), and St. Augustine tentatively (by his own admission "having gone back and forth, I find") opined in favor of BoD, but then forcefully retracted it after he matured from battling the Pelagians and issued some of the most anti-BoD statements in existence.  So if anything the reality is the OPPOSITE.

I am SO TIRED of INTELLECTUAL DISHONESTY where people just impose their bias onto their reading of the evidence and then apply cognitive dissonance to ignore the evidence contrary to their perspective.  I'm just absolutely sick of it, and I'm going to call it out, including with insults, because that's what it deserves.

If you believe that people can't have invincible ignorance, then this topic should prove otherwise. Both sides hold strong to what they believe.

Ignorance of an aspect of the material world is not the same as ignorance of the true God. 
If a person can be saved without knowing the true God Jesus Christ, then His passion and sacrifice is pointless. Moreover, there is no point in spreading the Gospels, and all of the martyrs, who were murdered evangelizing in strange lands, died in vain.
