If I don't make these shirts nobody else will. Nobody else has the poor judgement and mediocre design skills to make shirts and hats that at least half a dozen people might like.
Really though, I'm a guy who likes guns and gun accessories.
Sarcasm gets me in trouble with civilized people so I apply that sarcasm to t-shirts. I like t-shirts. I'm 32 and I still really like graphic t-shirts. I don't like video games, or comic books, or incel hobbies, but damned if I don't like t-shirts with cool designs.
This is a creative outlet more than a business. I have a job that I love already.
I hope you find something that you want to wear.
