Give it time. When they win the CL, it'll be f***ing horrific.
Honest question, are Barça fans as obnoxious? I can totally understand that we might be. People of my age grew up when Barça won the league once a decade, but the young'uns are pretty spoiled.
In England? Not, really. There must be thousands and thousands of people in Newcastle alone who own a Barca shirt, but for the most part, I just add them to the pile of people who own Brazil shirts: people who appreciate attractive football.
I can understand kids idolizing teams like Chelsea, Barca, etc., but their parents should beat it out of them sharpish, tbh. It's a fine line between admiring Messi and being some kind of X-Factor, celeb whore.
