I want to tell a cop he is despicable for giving me a ticket
What makes you want to tell a cop he's despicable?
He told me I needed to be a better version of myself.
Do not argue with police over a ticket you get. You should instead contest the ticket in court and have your say there.
But I want to argue with him
It is better to be kind when getting the ticket. You can fight it later, being rude might make your fines worse or escalate the situation. Try to be careful.
