That is not even a good example of lying by omission. You directly altered the facts as I presented them by joining sentence fragments. In this case, the grandparent comment is replying to an article that mentions the Hagia Sophia in the same breath as buildings that were built as mosques and have gone through their entire lifetimes as mosques. The comment does not have to restate the article point by point. If anyone is guilty of lying by omission it's the article's writer. They've erased most of the building's history.
