The word "gnosticism" normally refers to certain historical belief systems. One can see a description in Wikipedia:
There may be some points of similarity between Flatearthism and Gnosticism. For example, they both use knowledge improperly based on Scripture. Their actual beliefs, however, are very different.
Calling flatearthers "gnostics" is giving very little real information about them and is potentially confusing. It is basically just name-calling.
.
Perhaps you know enough about gnosticism to realize that there have been diverse factions of this ideology, some of which share nothing in doctrine or practice EXCEPT the one common feature -- that they all use knowledge improperly -- some not having anything to do with Scripture but merely pagan traditions.
.
So to be a gnostic, all you really need to be doing is
pretending that you have recourse to a secret or hidden knowledge, often times it being something that the general public all around you is ignorant of, or even opposed to.
.
One group of gnostics might entirely disagree with another group, but they're both gnostics anyway.
.
If they were any more secretive they'd be a secret society, like the Freemasons.
.
What stands in contrast to gnostics is the contrary, that is, any group of people who form a SCHOOL or an ACADEMY or a CULTURE, or other such things, which stand in distinction AND separation from gnostics by the simple fact that all of their doctrines are open for all to know, and reasonable discussion of said doctrines is not a forbidden activity.
.
Check out the difference: Just try to open any reasonable discussion regarding the visible universe on any of these threads and you will be swamped with the same repetitious, inane garbage that they have already posted hundreds of times.
.
Most forums forbid trolling but apparently when you're a flat-earther you can troll all you want on CI.
.
While you are ostensibly forbidden from posting the same thing in multiple threads, flat-earthers do just that with impunity.
.
They do it again, and again, and again, and again, and again.......................
