Is it time to start calling out bad cyclists?

Do you see what you've done there?
At the risk of patronising you further I am guessing you are young; under 18 maybe? Just calm down a bit, be less defensive and less sure of yourself. We all have stuff to learn.

only defensive becouse i get criticized straight away so oviusly it anoyed me, would of thort fellow riders would be abit nicer

and no im 19, and i actualy came to this site to learn more about bikes, pretty much all i do...
