For enrichment, we start by reading and reflecting on a **“published poem”**, suggested by someone in the group. No advance preparation is necessary. But feel free to check out some of the poems we’ve read [here](https://docs.google.com/spreadsheets/d/e/2PACX-1vSyE_wCLQCPHRrKmN5F9tOIeeRQUZESxjRXGVBoCF2uU8Gm0_d0uECiCBCQXEy6ksxfsBOhtRIOpW3T/pubhtml?gid=0&single=true&widget=true&headers=false%22%3E%3C/iframe%3E).

Next, we **share our work and offer feedback**. Depending on attendance, everyone gets \~10 minutes to use as they like. (No need to share, though; you’re welcome to come even if you prefer just to listen.) We maintain a **Discord server** to help share our work and communicate outside our bi-weekly meet-ups. If you haven’t used Discord before, take a moment to download it and create an account before arriving. When we meet you on Saturday, we will add you to our server, the “DC Poetry Workshop”, and can help you navigate the app if you have questions. Finally, if you plan on sharing a poem, consider how you will do so. Some options include: * Print 5-10 copies to distribute in person * Take and share screenshots in the Discord chat. * Copy the poem into a google doc, change sharing settings to “anyone with link”, and copy the google doc link into the Discord chat. Most importantly, we’re excited to meet you! Catch you on Saturday, Diego / Ian / Cayden / Nate / Otasha / Lia / An

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Facing Fascism,”** on the history, hallmarks, and lingering power of a deadly ideology, with Kevin Matthews, professor of history at George Mason University and teacher of courses on early 20th century European history. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-facing-fascism](https://events.ticketleap.com/tickets/profsandpints/nv-facing-fascism) .] Few political movements have aroused as much anger and fear as fascism. But despite its legacy of violence, persecution, and genocide, fascism continues to hold a strange attraction to many. Join historian Kevin Matthews for an in-depth look at an ideology that brought death to millions in Europe and yet continues to deeply influence our politics and culture. Dr. Matthews will start by discussing how the ideology of fascism arose in the aftermath of the First World War and took hold in Europe in the 1920s and 1930s. To give you a better grasp of what exactly fascism is, he’ll discuss its central themes: Anti-democracy. Extreme nationalism and anti-communism. The use, or threat, of violence in politics. Rejection of established values such as scientific objectivity. Denial of equal rights, especially for women. The assertion of power where a power vacuum exists. We’ll examine the rise and fall of two notorious fascist dictators, Adolf Hitler of Germany and Benito Mussolini of Italy. For a time it was believed that fascism died in the ashes of the Second World War, but it clearly didn’t, and we’ll look at where it remains a political force today. Finally, we’ll examine how fascism continues to permeate popular culture in ways that trivialize it, popping up in music from punk to Madonna, with its latent eroticism making it the subject of films such as *The Night Porter.* Having been called “the most self-consciously visual of all political forms,” it enlisted fashion leaders to produce uniforms and continues today to inspire a look known as “Nazi chic.” Dr. Matthews previously has given fantastic Profs and Pints talks on Ireland’s fight for independence and on World War II German submarine attacks off our coasts. He’s sure to leave you with a much better understanding of fascism and a recognition that is has hardly gone away. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.) Image: Benito Mussolini and Adolf Hitler during Mussolini's 1940 visit in Munich (photographer unknown / public domain).

Whether you've never done improv before, or you've done it for so long you knew Del Close on a personal level, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup** for some fun and games! The idea behind improv is to create entire scenes from scratch based on a suggestion from the audience. This can be done in game form, like *Whose Line Is It Anyway*, *ComedySportz*, or *Wild 'n Out*; it could also be done to tell stories, like *Middleditch and Schwartz*. Our meetup, which is central Ohio's longest running (and free!) weekly comedy event, brings the games (and occasionally different forms) for you to play in a safe, supportive, and compassionate environment. Not only is it a lot of fun, but you get to work on thinking faster on your feet, plus it's an excellent way to meet new people and make friendships that'll last a lifetime! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "Yes, And" that you'll have fun!
