Let your aggression go unchecked, just complete the sentence, offer an explanation if you feel you must.
I love Chicago, it is one of my favorite cities in all the world and I've traveled around. But White Sox fans are Assholes. I'm from Michigan and whenever I am in Chi-town and I meet a Sox fan they try to berate my precious tigers (and given how much the tigers sucked for most of my life it is still a sore subject). Cubs fans complement me, because they know what it is like to root for a franchise that won't perform.
(Cubs fans, keep being awesome!)
