I may be misunderstanding you here, but your comments feel to me as if they're based on an assumption that everyone in society faces more or less comparable levels of offensive behavior. For instance, to my eye, your argument about lawyers only holds water if it's based on the assumption that lawyers (as a group) routinely face a level of marginalization and abuse that women (as a group) do. In point of fact there's no urgency about banning lawyer jokes, because lawyers are one of the most respected professions in our society (as measured by various surveys about social status, etc.). Through some combination of talent, hard work, and good fortune they have wound up in a group that suffers very little discrimination. When people do make jokes about them they may find it unpleasant, but at the end of the day they're still more or less on the top of the heap. Women, on the other hand, face a thoroughly entrenched social structure that treats them as less capable and less important than men. There's a recognized problem that many women feel uncomfortable in technical circles, and offensive jokes are a real part of that problem. So every offensive joke about women needs to be understood against that background: it's not a one-time irritation, but part of an ongoing pattern. So attempts to discourage those jokes aren't just "nobody should feel offended, ever", they're one small step that we can take to fix the much larger problem.
