While I’m loathe to discuss the presidential race or the existence of God with strangers or even close friends and family members, I’ll gladly enter into conversations about whether it’s plausible that Joan did what she did with the dude from Jaguar in that recent episode of Mad Men, or why my beloved Packers will return to the Super Bowl this year. And I’ll do this even if I think the other person disagrees. If we end up jousting verbally for a few hours, it’s still fairly certain that we’ll be friends at the end of the night. I wouldn’t be as confident over a difference in party affiliation or spiritual beliefs.
