I can give you a real-life example of a child who had his MMR but still got measles because of the low compliance in their area. He was so ill (complications) that he ended up in hospital. So finishing one of your sentences with "lol" doesn't go down well here....
The "I'm fine and so is mum" stuff is a crock too... just because you don't know people who's babies died/became blind/men who became sterile etc etc, doesn't mean it didn't happen. Do you bother to put your child in a car seat? Because in the 60's they didn't worry about it.
It sounds as if you're trying to justify a choice that you're not convinced by either. Don't know if this will help:

You need to make the choice based on what you want, but don't expect everyone else to condone it when you are risking their children, and particularly very small babies who don't yet stand a chance. Now that we've all been immunised, children are, if anything, more susceptible to it than they were before. That might make you angry, but it appears to be true.
As to behavioural changes - if you can swear that your DC never has an additive cross their lips, has never been exposed to another virus/chemical overload in his life, then....... you may be able to prove, where no one else has, that there is a connection with MMR.
