Here is another point of disagreement. I believe in positive rights. I believe I have the right to education, healthcare and more.
I also think rights are timeless. Throughout the history of the humanity, one human always owed it to another human not to attack them or their property. However, to say that cavemen owed each other healthcare is absurd.
Well I believe rights apply to everyone alive now and in the future. There is no point worrying about people who lived in the past because they are dead now and there is nothing we can do to help them.
