New Zealand's antivax fanatics may be less than 1% of the population, but they have given over to raving hatred, and threaten others with violent death as well as death by Covid-19.

Letting this violent hatred stew will encourage them to get more violent. I suggest that the government adopt a policy of vaccinating everyone that is arrested (in the absence of medical reasons not to). Once they see that vaccination is not a bad thing, they will find it hard to keep the hate going.
