Allow me to disagree. There are few users so unfamiliar with anything as my 4 years old son. Yet our PC's boot menu has not represented a problem for him, or for my wife who is completely uninterested in technology. In fact, I have yet to find someone who is confused in the slightest by a boot menu.
But that's not the point. The point is that you cannot pretend to win an argument by playing the offended card. At most you will halt discussion and poison the relation with the community. That's too high price a price to pay for wining an on-line discussion.
People that are easily offended are as dangerous (if not more) to a healthy on-line community as people that are too prone to aggressive behavior. Note that I do not say "prone to offend", and that's for a reason: offensiveness is a relative personal interpretation. Anybody can choose to feel offended by anything, no matter how unreasonable may it seem.
