I am disgusted with anyone who mains Warwick and considers him to be hard-to-play

Recently, or whenever I play against the enemy team, there is a warwick. However, these players further enrage me by saying something along the lines of,"Warwick is a expert-level champion who I proudly main." In my personal opinion, Warwick is someone who should be left for mainly beginner summoners or people who are struggling or still learning the grasp of the game instead of silver II players with champion mastery 5 on him. Am I just being whiny or is there some level of reason to my frustration.
