There you are, gathered with relatives ‘round the Thanksgiving table. Your spouse is carving up the bird, the kids are fidgeting in their dress clothes, your workaholic brother-in-law is glued to his iPhone, Uncle Jimmy is deep into the good scotch, and your mom is chattering on about how she hopes the stuffing didn’t dry out while she was helping your sister make the gravy.

Then it happens. Someone mentions President Obama. Or taxes. Or Rush Limbaugh. Or voter suppression. And suddenly, your dad is ranting about socialism while Aunt Myrtle lectures your sister about the ho-mo-sex-ual agenda. Your brother-in-law stops texting long enough to make some crack about pro-rape Republicans, which sends Uncle Jimmy lunging for the carving knife.
