"The argumentum ad hominem, is an attack on an argument made by attacking the character, motive, or other attribute of the person making the argument, rather than attacking the argument directly."
This is usually regarded as a logical fallacy; but most of the time it is Not - and especially in a world ruled by evil liars, hence permeated by Satan-serving lies.
In such a world the single most important fact to establish is the nature and motivation of the arguer of a purported source of information - in other words, (here-and-now) all argument ought-to-be 'ad hominem': directed towards the person (or institution/ organisation) making an assertion.
Since this world is ruled by a single, linked bureaucracy: The System; and since The System communicates with us via the Public Relations (PR) interface and the Mass Media (which now structures and controls what used-to-be autonomous sources such as academia) - the main task we have is trying to understand and interpret PR and Media communications.
It ought to be clear that it is utterly futile even to try and analyse and compare the fire hose of PR-Media propaganda which deluges us every day (and which is, for the past few months) mandatory - if we fail to know the latest diktat on, for example, social distancing; we might get a hefty on-the-spot fine. Such a task would be combinatorially impossible; as well as more than a full-time job and intrinsically corrupting.
Fortunately, there is an alternative; which is to make an inference about the motivation of the source/s of communication; and understand and interpret the communication on that basis.
And (again fortunately) that is easy; because we know (we ought to know) that all the highly prioritised and sustained information which comes to us from PR and the Media emanates from a unitary origin that is an evil liar (or, more exactly, a relatively small community of evil liars).
There we have it! An immediate solution to the much-agonised-over problem of Information Overload!
Of course; it means that the majority who assume that the PR-Media communications are basically well-motivated and truthful will call you a 'conspiracy theorist' - but, we can put up with that (I assume?) when we are about the (clearly more vital) business of our theosis and our salvation!
