Long as you don't buy it and run around telling everyone BR this and BR that and not actually come here at all then you're alright. Which isn't the case since I've seen you walk the halls here. Support what you like, contribute to, support what you like
I think under your aspect for actually contributing to the site with an article (Glenn or someone up top approved it) would push you closer to purchasing one and spread the word, you have a good story to tell if anyone asks you about your jersey.
Simple point here, you can wear what you like but don't think you wont get criticism about it. I hear all the time about how my dad wears a clevland browns shirt, he always wonders why people say things like "browns suck' or 'how bout them browns'. He's not a Browns fan, he doesn't even like football. He wears the shirt because it fits him, he doesn't realize fanbase of the nfl

Swear our society as a whole wants to be judged regardless.
