The answer is: they don't care.

When you decide to align yourself with a decision for mass death, you need to make yourself comfortable with it.

To make yourself comfortable, you tell yourself a story.

This is their story. https://twitter.com/Eugene_Scott/status/1264564513657028608

Powerful people decided that rather than make the changes necessary to save lives, the virus will be allowed to have its way.

These people are aligning themselves with this decision, and would like to get on with it without reminders of what they're doing.

Masks are a reminder.

Masks are a open confession that there is a pandemic, which can be alleviated through preventative measures.

Which reminds everyone that deaths can be prevented.

Which convicts those who have decided not to prevent deaths of their decision.

They dislike being convicted.

We'll see reasons offered why these deaths weren't particularly tragic.

Seeing Covid deaths as tragic leads to questions asking how these deaths might have been prevented.

Those are questions people who have decided to not care would rather not see asked, much less answered.
