There is not one illusion that does not offer comfort (no matter how perverse the comfort is) ones ego can take comfort in strange things.
Especially in illusions of suffering, those offer comfort too, because the fallacy of absolutes isn't demonstrably false, as illusions can bring much more than just comfort and hardly all illusion brings comfort, regardless of how twisted the logic is "some people find comfort even in what some don't find comfort in, there in the absolute always find comfort includes those that do not, implicitly, when you refer to those exceptions"
Oddly you defended the quote and it's false conclusion and utter nonsense or lack of substance that it had and the character of the liar, hypocrite that peddled such nonsense, instead of questioning or realizing "hmmm absolutes and extremes, that's the language of fools".
Its foolish not to explore extremes and absolutes (please never try to build a bridge). Why would I defend a man accused of being liar? It is indefensible. I will assert that all human beings lie. The quote also asserts something which may not be totally accurate, however useful in understanding ones dependence on the "illusion of their identity" or more accurately why we create illusions to identify with. Isaac Newton has developed ideas which assert occurrences which are also inaccurate, however they are useful for designing bridges. If someone did not try to understand the extreme of Isaac Newtons theories, we wouldn't have realised they are inaccurate.
If we look at the sentence you take issue with.
You would have to give me an example of an illusion, that one can identify with, that does not give some level of comfort or some level of security. People have illusions of loved ones suffering all the time, so that they can take comfort in them being a victim. There is a whole industry built around the illusion of suffering.
