if you are not good enough to compete no will look down on that because you are not hyping yourself up to be something that you are not, some one who competes. If you are really good and do not compete you will hear some shit like "bro.. what the fuck... you need to enter some tournaments"
you might get some occasional terd that will talk shit but in all reality he sucks and you should not be listing to him anyway..
do not worry about it, train hard and everything will follow.
