Bravo. Now why don't you explain, in your own words, how your moral/ethical worldview is based on absolutely nothing, seeing as how the entire universe (including the human race you claim to be so fond of) are nothing but a meaningless coincidence hovering over the precipice of oblivion. Is it because "well, we're here, so we might as well pretend there are rules so we can all get along?" Something like that?
Let's hear a defense of absolute meaninglessness and oblivion as the basis of law in your own words.
The Principle of Reciprocity, a.k.a., the Golden Rule, is the basis of all the claimed rights.
Do not do unto others what you do not want others to do unto you.
As simple as that.
