No. You do it because you're a narcissist. You do it because you are scared. Scared of being forgotten. Scared nobody will pay attention to you. Nobody "falls" into roles. People put themselves in roles. The role you've put yourself in is to inject your OPINIONS In on things. You mask them to yourself as "truths" so you can provoke reactions. Whether this reactions are positive or negative, it matters not, because you are only after the end result of attention. Hints narcissism. Otherwise you would take your opinions and commentary to another place where they are more well received. To a group of like minded people, but inside you're scared. Scared you'll never be accepted. Scared you'll never fit in. Scared nobody will ever like you. You take on this "persona" because you want to fit in so bad but fear you'll never be able to, so you would rather play the opposite side of the fence and be "different". Be "punk". Be outside the norm.
It's all fear, John. A scared little boy, and the pattern follows you everywhere.
