There is a difference between the size of the observable Universe now and the size when the light was emitted. It does not violate relativity to state that objects that were 14 billion light years away when the light we see from them left are now much farther away due to expansion.
Furthermore, your reference to relativity is also incorrect. The expansion of the Universe is not caused by objects moving away from each other, which would be limited by the speed of light. The expansion of the Universe is actually an expansion of space itself, which is not limited by the speed of light. You should look up the "metric expansion of the universe".
In general, relativity is known to be incomplete on a cosmological scale. The situation is much more complicated due to the existence of dark energy and dark matter. You should read about the Lambda-CDM model if you want to learn more about the state of modern cosmology.
I didn't quote you or claim you said anything. I made some assumptions about why you made certain statements like the fact that you think the Universe being ~90 billion light years in diameter violates relativity (it doesn't and this is the currently accepted estimate for its size).
You could just clarify your statements/reasoning to try and progress the discussion instead of getting overly defensive.

I was the one explaining to the OP of the thread that the universe is 90E9 ly in diameter (and also, just to clarify for the future so that it doesn't get mixed up yet again, that this is just an approach based on what we know about the history of the universe), it is therefore ridiculous that I also said that it violates relativity. So, sorry if I'm "overly defensive" about you mixing everything up and me having to use my time to answer you so that you don't twist everything I said on the thread.
