It would be very ambitious to presume that any major issues could actually be fully resolved here. Perhaps one or two. However, what is expected more regularly is a conditional resolution. Both debaters can conclude that belief in A makes sense given belief in B.

One clear (though not particularly insightful) example is, a pro-life debater and a pro-choice opponent might both be able to agree to the following:

If one believes that a fetus is in every way a human being, he/she should consider abortion to be murder. If one believes that a fetus is in no way a human being, he/she should have no moral qualms about abortion.

It may seem like such an incomplete resolution is a pointless place to end a debate, but if you think about it, it saves a lot of time in future debates. Readers who are discussing an issue amongst themselves can avoid taking the time reaching the same conclusion, and focus on taking the argument further. And, perhaps, one day they could debate the topic again on this site, and demonstrate their findings here.
