"Anyone can come to our event." That’s what we tell ourselves - we the people who program and labor over our events. We don't bar anyone from joining the fun, and the only barrier may (or may not) be a ticket price or alcohol-related restrictions around age. When we do price our events, we make sure they're affordable for our demographic and right along with our competitors’ prices.
But the real truth is that not everyone is actually welcomed to our events. Whether we want to admit or not, our event send signals about who's welcomed and who isn't.
