.., but I'll stand by what I said - my definition remains consistent under all circumstances, the 'conventional' definition does not - that appears to be factual to me (mathematically correct). IMO, there should be two different terms used, but I certainly don't expect Websters to adapt to my view. But I can still point out the inconsistency, no?

I haven't the foggiest idea what you're getting at. What would it mean for a definition to be inconsistent? A statement or theorem, or the conjunction of a set of those, is inconsistent when it is always false. Definitions can be appropriate, useful, traditional, and a lot of things, but they can't be true or false, hence they can't be inconsistent. And what does mathematics have to do with factuality, anyhow?
Well, this is probably a waste of time, but humor me (I'm just having a bit of odd fun, discecting the English language) and I'll try to explain.
First off - ' What would it mean for a definition to be inconsistent?' , well the definition of 'inconsistent' is: "Not staying the same throughout; having self-contradictory elements."
So here is where I see the contradiction in the general usage of these terms:
An income tax can be levied as a:
A) Progressive Tax- Higher income is taxed at a higher % tax rate.
B) Flat Tax- The same tax % rate applies to all income.
C) Regressive Tax - Lower income is taxed at a higher % rate.
D) Head Tax - every person pays the same amount (as opposed to the same rate).
Something cannot simultaneously have a negative slope and have no slope. So something cannot be both a flat tax and a regressive tax. Yet...

flat tax definition
A single tax rate that applies to everyone obligated to pay the tax. Sales taxes are flat taxes.
and the same source...
Regressive tax | Define Regressive tax at Dictionary.com
regressive tax definition
A tax that takes a higher percentage of low incomes than high ones. Sales taxes, especially on food, clothing, medicine, and other basic necessities are widely cited as examples of regressive taxes
So there's a built in contradiction, no? It can't be both.
Consider a $1 sales tax on a bottle of liquor. I would call that a "Flat Tax" - they don't ask your income level at the cash register, it isn't assigned a different amount or rate based on income. So I call it a flat tax, and that also matches the definition above.
In this thread, that $1 liquor sales tax is being called 'regressive' because the $1 represents a higher % of a low income than a high income - again, it can't be both. But there is a second inconsistency:
Chauncey has a $100,000 income, and buys 100 bottles of liquor a year.
Joe has a $50,000 income and buys one bottle of liquor a year.
In this case, Chauncey pays a higher % of his income on this tax than Joe ((100/100,000 > 1/50,000). So how can it be 'regressive'? It is only regressive under certain circumstances, but it is always 'flat' (levied independent of income).
The English language is imperfect. I'm just pointing out that this is one of the imperfections, and it makes discussion difficult. I prefer to stick to the words that are consistent. Without extra words, I can't know what someone means when they say 'regressive'. As I see it, 'regressive' should be applied to how a tax is levied, and there should be some other term for it's effect. Sure, I'm being pendantic here ('Being finicky or fastidious with language'), but I think it comes from some of the programming I did - it was always trouble if a single variable ended up getting used two different ways, or two variables were used to represent the same thing.
