No, I'm not saying that parents want you to give your permission. I'm saying that calling them "child abusers" and "murderers" is not helping their children nor does it help the deaf community. You also make it sound like the children are dying of meningitis in droves but actually it's relatively rare (although very publicised) and it's preventable. I can understand anger at a parent who doesn't vaccinate though.
Now, since you brought up meningitis what you do you think about the fact that meningitis incidence is at least 4 times more common with deaf children even without CIs compared to hearing children? Wouldn't this be a potential additional risky problem for children with those affected etiologies who are deliberately conceived as deaf through IVF? How do you feel about that?
Uh... yeah, not happening. The risk of meningitis in Deaf children is distinctly linked to the whole drilling holes in heads without vaccinating thing. It's not something you're just born with. Even if the parent does the responsible thing and vaccinates, NO vaccine is 100%! There are still other risks involved in surgery, meningitis aside, and all.
I call people who kill other people murders. There's no better word for risking a human being's life, without their consent, in pursuit of their 'normality'. If it's one in ten or one in a million- it's a life.
