I have a cousin like that. If he see's someone he knows and they have something on their car or what ever of a team that he doesnt root for, he will either a) take it off or b) put a sticker or something over it. I told him that is damage to personal property and he doesnt seem to care. Im like well I care, it isnt your place to do that. I told him that there are many people who doesnt like HIM so shoudl we all STICK A STICKER ON HIS FACE ?? He got pissed off and walked away
