An Antivaxxer is like someone letting their kids swim in shark-infested waters because they're afraid the bridge will fall.
The Antivaxxer is really just engaging their child in an elaborate cosplay of being alive in the 13th century.
The Antivaxxer is one who, when sending their children to a foreign country, is basically involved in low-grade biological warfare.
The Antivaxxer is engaged in the equivalent of not feeding your children so they don't choke.
The Antivaxxer is not deserving of free healthcare given that they are willfully adding more disease and sickness into the world.
The Antivaxxer is engaged in the equivalent of not buckling your kids in because you heard about a freak accident where the seat belt cut a child's midsection in two.
Antivaxxer is like people that don't get bitten by mosquitos so they don't spray their kids with bug spray then get confused when their kids have bites.
