Bobert, old buddy,

I think you give him to much credit?

"I have also presented several examples of universities like Harvard, Yale and MIT surveys that use the two terms."

It appears that he is saying that Harvard, Yale and MIT are examples of universities. Which is true.

Then he appears to be saying that the whole of each university uses these things universally. Which is far from true.

Then he implies that since someone in the university uses these things then that proves that your criticism of his use of them makes you a liar.

This is such confused and silly balderdash that it makes it very difficult to find the lie.

To prove that it was a lie, you have to first determine whether or not he has said anything. I don't think that he has. He has tossed out a lot of words. Some of them with some credibility, for example "Yale." But how can it be a lie when it isn't even a coherent English sentence?
