Those terms are idioms commonly accepted to mean certain things.
To an extend means: Somewhat; partly; in a limited way or to a limited degree.
For the most part means: Mostly; in general.
In short neither represents the all.
I’ve known of activities, not documented, that I would never have heard of if not for the person whom I talked to. That means that there exist at least those activities, that many people don’t know about.
I partake of some PvE activities that are not the norm, some have related documentation, some do not.
Eve is a sandbox, such occurrences are almost guaranteed to happen when people are free to do pretty much as they please with what they have been given.
Therefore you have no idea about what actually requires intelligence to perform. You know of things that don’t require intelligence, but that does not talk about what you don’t know.
I also know of things that do require intelligence to perform. I never stated that I know of all activities, nor did I judge upon them; this is where those idioms/phrases, to an extent and for the most part, come into play.
You are in the typical fallacy “I can prove that something does not exist by my experience”.
No, I am not; you however have tried to misrepresent what I said by stating that commonly used idioms, which in this case are phrases that completely refute your version of what I said, have no intrinsic value and inferring indirectly that they don’t mean what they actually mean; not that I’m sure the term intrinsic value can actually be applied in that way.
In short, while stating that you believe I have presented a logical fallacy, you’ve constructed the very definition of a strawman argument, which in itself is a logical fallacy.
Fallception indeed.
