The most disturbing image I saw in my life

[Angrboda]

This is an example of the fallacy of poisoning the well.  Implying that anyone who disagrees with you is inauthentic and unrealistic and therefore must be wrong.

How come?

Literally, I was saying:

1-The monks who wrote the Bible of the Council of Nicaea cannot be trusted or taken as an authentic writers because, the Well is literally poisoned: so anything produced by them is also poisoned.

Example: trusting the testimony and tale of a Mafia boss and his gang in an event they witnessed from afar.

2-The political motive was enforced since the gathering of these Monks took place by Constantine's order, command and advice.

Example: trusting the story of the CIA in a case about internal questioning.

Sorry dear. The well is already poisoned. It's not a fallacy.

It's a fallacy because a person being inauthentic and unrealistic has no logical connection to them being correct or not. That you don't understand this is simply another side of your ignorance. You have to demonstrate that any inauthenticity or unrealism influenced their claims, not simply assume it in order to undermine their claims. Essentially, assuming it turns your argument into a form of argument from bare assertion, aka an ipse dixit argument, i.e. asserting that "their claims are corrupted by their biases" without any actual evidence or support for your belief. But I don't expect you to grasp these facts any more successfully than you grasped that plasma is physical.

(As an aside, Constantine's influence on, and the extent of the changes which occurred as a result of Nicea are frequently exaggerated by ignorant morons like you.)
