and this is the reason why we question why people should have rights. Because it turns out, people should. And there are a lot of rights people don't currently have.

Questioning why you should, often leads to instances where an existing non right, is brought up, talked about, and then people may decide it should actually be a right, the right to die for example. Medically assisted death.

And besides, it has the benefit of forcing you to think for yourself, which often forces you to think about the underlying reasons as to why you believe something, which pushes you to find a reason to believe it, and if done sufficiently. Leads to a very stable principle base, leading to very consistent, and fair beliefs. Though unfortunately this requires you to think about particular things most of the time, trans rights for instance. But like i said, it leads to me believing that people should be able to do what they want, because having more options at your disposal, leads to a happier more complete life, that you will be capable of getting more out of.
