I couldn't agree more. First of all, I'm a guy - so I definitely have noticed the lack of "male" fabric in the quilt section. Second, I make charity quilts for Quilts for Kids and they've requested more quilts for older boys. But it's hard because there isn't much fabric that isn't either "cutesy" or "girly" - two things older boys won't go near. But it isn't just Joann's, it's the nature of quilting fabric, 99% of it is bought by women, so it is designed to appeal to women.
I've made a few quilts with apparel cloth (camo), some with marbled or variegated quilting fabric but in a bold pattern (a large lightning bolt), and some out of sports team material. Some quilt fabric I've thought about but haven't bought yet, because I don't know what to do with it, is flames, skulls, maps, black and white checkerboard.
