Was anyone else put off by "And, if you want to kill your ex-girlfriend, there's really no substitute for a ball-peen hammer"? I get it's a joke, but violence

Was anyone else put off by "And, if you want to kill your ex-girlfriend, there's really no substitute for a ball-peen hammer"? I get it's a joke, but violence against women, when used in a semi-professional context in a community of software engineers is one of those things that keeps more women out of the field in the long run. I'm not trying to be PC intentionally -- it just struck a raw nerve for me.
