For example, pls don't object if I quote from another thread
this sort of thing -
"The anti-vaxer reasons that uncle Bert gets hay fever, hay fever is hereditary and something to do with immune system, vaccine damage is also something to do with the immune system, DC are related to uncle Bert, and are thus more likely than average to suffer vaccine damage. They thus don't vaccinate them. The anti-vaxer believes that the evil quartet of doctors, scientists, govt and pharma conspire to under-report vaccine damage. All part of their thirst to play god, and make lots of money by making people ill, not forgetting generous measures of incompetence and stupidity. They reason that vaccine damage is under-reported so they don't vaccinate their children. I have never seen any attempt to quantify whether either 'the more susceptible than average' or the conspiracy theory could plausibly be sufficient to justify not vaccinating. It's incredible lame."
It's patronising, untrue, abusive in the extreme - and people defend it and agree with it! People acros all these threads at the moment. How can you possibly justify it if you are genuinely interested and concerned about child health?
I'm not talking about everybody who is generally supportive of vaccination - I mean the very vocal group who jump on every thread and suddenly start to be sneering and patronising, accusing people of being self-declared health experts and so on. There's no need for it. Unless you are very uncertain of your case of course. But if you're confident - there's no need for it at all.
