You didn’t actually provide any argument, just pseudo-philosophical drivel. Ideas and roles can be filled, but no two people are the same and so nobody can be precisely replaced. Arguing otherwise is juvenile, though you’re free to provide evidence of two identical individuals.

That’s a sad and scientifically inaccurate perspective. You must not know many worthwhile people.

Well, I can take joy in the pain of people who are regretting their votes because Donald is not building a wall/prosecuting Clinton. I really don’t have a lot of sympathy for those ones.
