There is none to skip. Just your inability to comprehend, possibly?
You are increasingly posting gibberish, which fits a pattern rapidly becoming a stereotype.
In the early stages, it looks like this:
"When the slander, insult, claim, belief is used as rationale for an action, or belief, then that first slander, insult, claim becomes an argument for the second."
2) In the collapse of your syntax, among other problems you lost the reference for "the second". What is "the second"? For that matter, what was the "first"?
You will never answer the questions posed in such replies, because you can't. Neither can anyone else.
It is an argument because it is used as the rationale for subsequent action / belief etc - -
It is a premise, a claim from which I drew a conclusion by further reasoning.
To see that it is not an argument itself, note that terms such as "fallacy" do not apply to it. Neither do terms such as "deductive", "inductive", "ad hominem", etc. Such terms apply only to arguments.
The color of a semaphore light, for example, is not an argument.
Just your inability to comprehend, possibly?
Comprehension of your intended meanings just highlights the distance between them and your posted language. Once sensitized by the flagrant examples, the abused readers find themselves awash in verbiage that reads like an attempt to outline meaning as a knife thrower or stencil inker might, by near misses - and reminded, over and over, of previous similar muddles and where they came from. So even subtler misses feed into the emerging pattern of posts like this one:
Example: "You're a fat, lazy layabout (insult) therefore you should get out more." The insult is used here as an argument for getting out more. See - insult used as argument.
Insult used in an argument, for an argument, to make an argument, etc - not "as", if one is being careful.
Part of an argument, in other words. You needed the rest - in particular the word "therefore" - to make an argument from an insult. Without the rest, you'd have an insult only - no argument at all, let alone an "ad hominem" argument.
That is not, btw, an ad hominem argument. Whether you intended it to be one is anybody's guess.
Here the argument "You are too intelligent..." is about the person.
It's a claim or observation of supposed - assumed, for the sake of the ad hominem argument it is part of - physical fact. Formally, in the given context, it's a premise. Add a few words - "therefore", "so", "because" - and you can make any of several different arguments from it. Only some of them will support interpreting that as an "attack".
(note the word "so" indicating that what became before in this example is the reason - argument - for what follows).
And your point is what, exactly - that I did successfully post an example of an ad hominem argument on my first try?
Your turn. Insult is not argument, remember. You need the "so" or some such word, and what follows, to make an argument of an observation.
I didn't say that that example was an ad hominem, nor that slander is a fallacy.
That's nice. You also didn't say lots of things that (unlike those) would be relevant here.
The point being, still, that paying attention to "who" might be of value in answering the OP question of "why". For one thing, it seems to indicate that something other than the strictly personal is involved.
