The whole discussion of religious objectors to vaccination reminds me of the religious conscientious objectors to the draft in Vietnam.
Seemed like it boiled down to 3 groups. There were the truly religious objectors, the objectors who magically became religious objectors the day they got their draft notice, and the third group who fled to Canada. I have yet to hear any pilots today in that third group.
Not trying to stir politics, this is an observation of history. History does repeat itself.
