Well, here's my view, and worth every penny you paid for it:
The piece is funnyish, but based on a rather antiquated stereotype of women (and men for that matter). I'm not all bent out of shape about it, it's just not my cup of tea. It seems kind of an easy take on the relationship. Some dudes really do conceal their guitar purchases, and some women really are jealous of the attention musicians give their instruments, so it rings true on that level. But that's the whole joke. Okay. No need to rain down fire on poor Aaron for what could at worst be called a lesser piece of work, and who does an excellent job overall of marketing Warmoth products and being a very open, responsive, and civil online presence. The only reason I'm expressing an opinion at all is to contrast it with the extremists. I would otherwise have kept my opinion to myself and gotten on with my day - which I recommend to anyone who can't discern between a joke and genuine sexism.
Carry on,
