There are 3 questions you should ask someone you disagree with.
Almost everyone has at least one issue they feel strongly about.
Maybe yours is marijuana legalization. Maybe it's abortion. Or maybe it's even an issue that's local to you, like whether your city should put in a trolley.
But somehow, in spite of all the information out there that you've carefully considered, there are all these "weirdos" around who feel differently than you do.
