"Everyone is doing it" has always been - and will always be - a terrible reason to do anything. "anti-vaxxer" is too broad of a term. That's like saying anyone who doesn't want to buy a Ford is "anti-car." They're not anti-car, they just don't want a Ford. Almost all the people you call "anti-vaxxers", in fact very much believe vaccines are modern miracles that have reduced or eradicated serious illnesses. Many of them get a flu shot every single year. That's not the behavior of an "anti-vaxxer." "anti-vaxxer" is inaccurate at best, and intentionally derogatory at worst.
