Seems to me that the interests are often not literally opposed, such that one group literally has “X” as a terminal value, and the other group has “not X”. More often, the goals are simply anticorrelated in practice, thus wanting “the opposite of what the other group wants” becomes a good heuristic. This is why calmly debating and exploring all options, including unusual ones, can be a good approach.
For example, in this specific situation: (1) legalize prostitution, and create safe conditions so that the prostitutes are not exploited; (2) create good cheap sexbots, or maybe rent them.
