Tar-Elenion
It was easiest to deal with your first long post in one reply, now I will reply to your shorter posts to Aragil and myself.
No one is saying that uruks are half-orcs. You are apparently debating that with yourself. What we are saying is that the Uruk-hai are Saruman's elite troops and they are probably a blend of orcs and men. As to uruks being an Anglicized form of Uruk-hai, neither you nor anyone else has yet presented a single piece of hard, uncontovertible evidence for this contention.
Moving on to your next post, I discussed the first Tolkien letter in my previous post. Cian's longer quotation from it shows that it does not mean what you implied it meant.
Moving to the second letter (once again a thank you to Cian for supplying a fuller quotation) it says: "But the penalty is, as you will know, to breed new Saurons, and slowly turn Men and Elves into Orcs. Not that in real life things are as clear cut as in a story, and we started out with a great many Orcs on our side ... Well, there you are: a hobbit amongst the Urukhai. Keep up your hobbitry in heart, and think that all stories feel like that when you are in them." Once again we see from the fuller quotation Tolkien is not saying what you implied he was saying. In the context of the letter orcs and Urukhai are not necessarily equivalent. The phrase "a hobbit amongst the Urukhai" in the context of Tolkien's writings would appear to be a reference to Merry's and Pippin's time in captivity during their trek across Rohan. Tolkien does not define Uruk-hai as the plural form of uruk.
Once again we are left solely with secondary sources stating that uruks and Uruk-hai are equivalent. There is nothing in Tolkien's writing to state this. It might indeed be a reasonable hypothesis, except for the fact that it does not explain Tolkien's usage of the two terms in LOTR. In LOTR he consistently uses Uruk-hai (always capitalized) to refer to Saruman's elite, sun-tolerant orc troops and uruks (sometimes capitalized, sometimes not) to refer to Sauron's large, soldier orcs. I find it hard to believe that this sort of consistency from a perfectionist, philogogist doesn't mean anything and that the terms are really interchangeable.

Nowhere in LOTR does Tolkien place Uruk-hai in Mordor. The only thing that even comes close is the reference to a "rebel pack of Uruk-hai" which can easily be understood as referring to Saruman's troops. Nowhere in LOTR are Saruman's troops referred to as uruks.
In any event I am not arguing that there were not differences between Sauron's Uruks and Saruman's Uruks. What I am debating is whether they were 'Half-orcs' or not. The Half-orcs are a seperate group, as is distinguished by the author. I am also debating that 'uruks' is the 'Anglicized' form of 'uruk-hai'.
