Once there was time when, if you were into graphic novels, B-movies or other fringe entertainments, you were considered a nerd. Today everybody’s a nerd. Being a sci-fi fanatic, having a collection of rare action figures or harboring a passion for video games no longer makes you unique, it makes you part of the mainstream. Case in point: From Friday to Sunday, Sept. 9-11, a vast array of above-and-below-ground pop-culture obsessions will be celebrated at the Wizard World Comic Con taking place at the Greater Richmond Convention Center. It’s a glorious, nerd-ball event with vendors, panel discussions, showcases and appearances by Kiss bassist Gene Simmons, 12-time Olympic gold medalist Ryan “Swim Shady” Lochte and wrestling superstar Dean Ambrose — to name just a few scheduled to attend.
