There Is a Prejudice I Have Which I Have Never Talked About in Public

There is a prejudice I have which I have never talked about in public: I believe that Royal Enfield / Bullet bikes attract a certain type of people who have certain personality disorders like narcissism and psychopathy. I am yet to see an exception. At least, this is the case with those who modify the bikes to be louder. The rationale is that a normal human would not be okay with disturbing thousands of people just for his vain pleasure.
