Correcting someone's 'your' to 'you're' does not make you a genius; it just means you are incredibly unpleasant. Studies in personality psychology have shown that people who are highly sensitive to grammatical errors and feel the compulsion to publicly correct them score significantly lower in agreeableness and higher in introversion. You are weaponizing syntax simply to assert dominance over strangers online.
