So i was having a discussion (using this word liberally) with someone on youtube called nomencIature1 who apparently believes i did such a poor job arguing that words do not have objectively valid meanings that he is going to make a youtube video about our discussion for the expressed purpose of "proving how stupid libertarians are".
anyway my argument went something like this, and this is going to be a bit abstract so try to bear with me. First we accept the following premises. 1) all words have objectively valid meanings 2) there exists a thing called a potato chip 3) there exists a thing called a hash brown 4) the difference between a hash brown and a potato chip is that the hash brown is thicker than the potato chip. Ok so then it should follow logically from these premises that as we gradually increase the size of a potato chip there should necessarily be a correct answer to the question of precisely when does the potato chip cease to be a potato chip and instead becomes a hash brown. So for example say the answer is 3.281740284 millimeters and if that is in fact the correct number that is the threshold than any claim that any number other than that number is the threshold is necessarily and objectively false.
I think we can all realize that this is a ridiculous conclusion so the big question is does this conclusion actually follow from the premises, because if it does than i think we can confidently assert that at least one of these premises is false and im pretty sure that if one of these premises is false than it has to be the first one.
anyway here is the video that we had our comment wars on

Hi.
The problem here is with your definition of "objectively valid." Think of a word as a variable mapping to a set. X, for instance, is "all things that are potato chips," while Y = "all things that are hashbrowns." Both X & Y represent *sets*, which may or may not overlap. Since the sets overlap, there will be potato-stuff values which will belong to both sets, in other words be both a potato chip & a hashbrown.
Does that make sense?
Edit: Maybe this is clearer:
[...] it should follow logically from these premises that as we gradually increase the size of a potato chip there should necessarily be a correct answer to the question of precisely when does the potato chip cease to be a potato chip and instead becomes a hash brown.
This is where things go astray. You assume that "potato chips" & "hashbrowns" are mutually exclusive -- something is EITHER a potato chip OR a hashbrown -- EXCLUSIVE OR. "Potato-stuff" can be both a hashbrown & potato chip at the same time, with both terms strictly defined (i think that's what you mean by "objective"). Another example is red & yellow: At what point does red become yellow, and wtf is orange? If we define colors in RGB, there's no question that the definition is rigid: pure red = 255,0,0, pure yellow is 255,255,0 -- any color in the RGB color field maps to one, and only one number set (or hex number, if you're a coder: red=ff 00 00, yellow=ff ff 00). The word "red" is a reference to a
set of colors having non-zero value R (of RGB), while "yellow" maps to all colors with both R and B having non-zero values.
TL;DR: Some words are strictly defined & map to sets, sets which may have members in common.
