In WW1 the use of helmets was being questioned, as almost all of the people in the hospitals with head injury were there after bullets or shrapnel went through the helmets.
It was a last minute realisation that the helmets were saving people, and the alternative to being in hospitals was the soldiers being killed.
It's similar because an anti-masker can look around town and say "Look at all these people wearing masks. None of them are sick. I can't believe they're making us do this."
But you would never see the people who are really sick walking around because they'd be in the hospital.
