Most black people in the US don't have the luxury of hosting dinner parties year in and year out and shrug off racism when their relatives are being killed by police, burdened with debt, treated unfairly by the justice system, lack the education to get ahead, struggling to make ends meet, dealing with microaggressions daily, and having their grievances constantly questioned by white people.
To answer your question my friends and family engage in a variety of topics at gatherings, whether they be dinner parties, virtual happy hours, cookouts, picnics, nights on the town or whatever. Politics, racism, sexism, climate change, the pandemic, religion, funny TikTok videos - pretty much anything in the current news cycle is fair game for conversation. For instance, last summer the murder of George Floyd and the Black Lives Matter uprisings were a huge topic among many people I know, even at work. As you might imagine the political views in my circle are pretty homogenous, however we don't always agree but we do respect and listen to each other's opinions. There are a wide range of ages, genders, ethnicities (yes some of my friends are white), nationalities, gay and straight in the mix.
