You should send him to some of these blogs and websites, have him take a gander at these "old woman" quilters:

Then ask him if he would like some chocolate syrup on those words he now has to eat! LOL
BTW, I have been quilting since I was in my 30's. I am 51 now, so maybe in his mind I am an old woman. I also ride a HarleyDavidson Roadking and have tattoos. So there.
