Also, people with pre-existing conditions ... are still people. It's not okay to accept someone's death just because they had an immunodeficiency. It's not okay that someone who was infected with a virus they might have survived dies because they also contracted SARS-CoV-2.

This is not a scientific argument.

One should not assume that someone who holds an opposing on a particular scientific point is somehow unemotional with regard to any particular issue.

When discussing a science paper, the science should be under discussion... not the morality nor the value judgement one may or may not have with regard to the subject.
