Your post sounds pretty good, especially when you don't conclude on what we are allowing by "letting them be", which is to continue the spread of a deadly disease.
There’s a vaccine that has an effective rate of well over 99.9% and is free for everyone in America. The “continued spread of a deadly disease” is among those who choose not to vaccinate. The vast majority of people getting seriously ill and dying in America chose to not get vaccinated AND not changing their habits.
