Flaunting one's profession doesn't automatically make them a better person. So, you wrote a novel. Big deal. So did a bunch of people. Is it published? It is? Big deal, so is a friend of mine. Here's the catch; those novels--just because they're finished--aren't always written very well, and most aren't published. And those published ones? My friend published his for free through an on-demand publisher. He makes perhaps a dollar off each sale. It doesn't make him any better than anyone else, and it doesn't automatically make his writing any better (I've read it, it's still very amateur).
So, you work in game development. Good for you? Your point? There is none. It's a job. That's all it is. You have military training. So, you went through Basic? Whoopie. You're still not any special, and really, your ass can still be handed to you. Basic training is an intensive exercise program with some basic (BASIC) weapons training, and that training would only apply IF you had access to those weapons, which most inactive service members will not have. Thus, it's moot.
Flaunting one's profession just makes that person an ass, and I have seen time and time again that despite all of their "worldly" experiences or "higher education," people are still idiots where it counts.
