Swansman can fight his own corner, but while it was a clumsy analogy, there is a point to be made there I think.
I have been pretty vocal here, and elsewhere about my views on anti-vaxxers. I think anyone that refuses vaccination for non-medical reasons is doing something stupid and contributing to wider social harm.
However there are degrees of stupid and I do have more sympathy with certain groups ( eg where reluctance is linked to a justified suspicion of authority) than with others (eg the middle class hippies I am surrounded by, the right wing 'individual freedom' loons or the conspiricy theorists talking about Bill Gates and 5G). So it doesn't seem quite right to lump them all in with Farage and co. Also we want people to get vaccinated, and making martyrs of some doesn't always help pursuade others. Better to understand the reasons and then try to quietly target those that are pursuadable, not least by politely dismantling the arguments of the proper nutters..
If it hasn't worked by now, then I suggest that it ain't ever going to work.
