Of course not. The classic saying is "It's not what you wear, but how you wear it" and that couldn't be more true. Half of selling anything is how you present it. Wearing a gaming hoodie does not automatically make you a "nerd" or a target for bullying at school or in social settings. It just makes you authentic. It shows you have taste, and more often than not can be a great conversation starter. The fact is: You don't know how other people will respond until you do something. Try it out! You'd be surprised at how many people are out there who like the same things you do. It's a way to potentially meet new people or forge a deeper connection to classmates and coworkers you already interact with. Half the time people hate simply because they envy a person who is presenting themselves authentically. Let other people's problems be their problems and let your fandom shine. You don't deserve any less than to be your amazing self.
