Will, you're absolutely right. You're opinion is as welcome as anyone elses'.
I had to "share my opinion" with a guy today at 'Cracker Barrel'.
I was eating breakfast when I overheard the waitress ask him who he was rooting for, Cowboys or Giants. He told her he hated both teams, (I'm fine with that), and I didn't hear what his answer was.
So, he and his wife are looking at the paper, and I over hear him mention something about the Jessica Simpson B.S., followed up with "Romo the homo". (steam begins coming out of my ears at this point.)
I finished my breakfast, walked over to his table, (proudly wearing my Cowboys sweatshirt), and asked him, "Are you an Eagles fan by any chance?"
His response, "Yes I am". At this point
I shared my opinion with him..."I thought so by your display of a lack of class.", and I walked away before it got worse.
