The answer to the question “do crazy people know they are crazy” is a firm “absolutely not” and the comment you’re replying to proves that. Don’t bother replying, it’s always the same. If they reply at all it will be with a mix of half-truth personal anecdotes, scientific-sounding nonsense, paranoid delusions and if you’re really unlucky outright antisemitism. They are far gone and they don’t know it yet, there isn’t much you can do to stop that purely online. Just feel sorry, move on, and petition your representatives to tackle the mental health crisis befalling many of us.
