Here we have an explanatory, mildly argumentative thesis that enables the writer to express an opinion. We infer from the use of the word convincing that the writer will judge the various reasons for protecting the rights of AIDS patients; and, we can reasonably assume, the writer himself believes in protecting these rights. Note the contrast between this second thesis and the first one, where the writer committed himself to no involvement in the debate whatsoever. Still, the present thesis is not as ambitious as the third one, whose writer implicitly accepted the general argument for safeguarding rights (an acceptance he would need to justify) and then took the additional step of evaluating the merits of those arguments in relation to each other. (Recall that Anthony Jones's plan was the "most sensible.")
It is interesting to note that the Federalist papers are unique, as shown in this paper, because of the extreme amount of thought that was put into the design of the Constitution, as shown in Madison's original thought process that were penned in 51. Many, if not most, changes in institutional design, occur as the reactions of shortsighted people to what they perceive as more-or-less short-range needs. This is one reason the Constitutional Convention was a remarkable event. The Founding Fathers set out deliberately to design the form of government that would be most likely to bring about the long-range goals that they envisaged for the Republic. What is most unusual about Madison, in contrast to the other delegates, is the degree to which he thought about the principles behind the institutions he preferred. Not only did he practice the art of what nowadays is deemed institutional design, but he developed, as well, the outlines of a theory of institutional design that culminated in this essay.
