Kingston's Policy & Politics Book Club is intended to be a group for people of all political persuasions to meet for civil discussion of the issues of the day. (They've been doing so since September 2015.) They meet at Rough Draft on the fourth Tuesday of every month, and they're always happy to welcome new members. Attendees get $1 off their first round of wine or beer.
August's book is Rules for Revolutionaries: How Big Organizing Can Change Everything. Get more info and RSVP at meetup.com.
