What are some advantages or pro's about gerrymandering?

That depends on which kind of gerrymandering is being implemented. There is racial gerrymandering which is designed to benefit certain racial minority groups, or other kinds of gerrymandering which designed to disempower them. There is partisan gerrymandering which might, like Bandit's answer aluded to, help both parties re-elect their incumbents, or there is partisan gerrymandering which might help one party at the expense of the other.

I'm sorry; I know you wanted a laconic answer, but the question itself is so vague that it is impossible to answer it without discussing the different types of gerrymandering that there are. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
