There are certain things we can look past. Todd chumming it with some Packer fans at a tailgate to score some tasty Bratwurst and some Spotted Cow beer is acceptable. They share their tasty eats with us, we allow them some Goose Island 312 and some Polish Sausage in exchange.
It's a beneficial, and temporary truce for the betterment of all our stomachs.
Plus, we're not Monsters. We have a certain level respect for the fans in green and gold, we may not particularly agree with them, and they take the whole "ownership" thing way too far, but they are a loyal fanbase that stood by their team when we were kicking the crap out of them back in the day, much like we stick by our team these last few decades when they've been getting the better of us.
