What if this so-called "herd immunity" described does indeed work by not allowing a disease to get a hold? It could only do so by sacrificing some of the most weak and vulnerable to adverse vaccine reactions, including death --is that acceptable (maybe in today's Amerika)? With our modern medicine and bioterrism sensitivities, it is highly unlikely that a disease would spread far in the manner you described.
I've seen doctors make SO many mistakes...and they totally avoid preventative/nutritional aspects of medicine. What about the parent who "knows" that their child seems to have food sensitivitious (through family history, close observation), but can't perform medical tests to prove it? Must they still submit their child to vaccinations about which the doctors don't even know the contents? Ever try to get a hold of the vaccine insert to read? Good luck; you must be provided one by law when you buy aspirin, but you are treated like a space alien if you ask for one for DPT or MMR. A child I know has wheat sensitivities, and not a single doctor in the entire prestigus could tell the parent whether the shots had wheat/gluten- huh? Who's being irresponsible there -- the ignorant doctor or the parent who seeks further info?
I don't know all the facts in this case, so it's hard for me to say what's going on -- were there simple steps the parents could have taken earlier which would not have infringed on their consciences but meet the letter of the law? That being said, I think it is better to run the risk of a few children being "left behind" by fake/irresponsible homeschooling parents than to regulate the vast majority who are doing it right, in order to leave sacred the right of parents to direct their children's upbringing (it may be too late in terms of precedent, since we've swallowed the hokum of mandatory schooling). There are already laws against child abuse, those should suffice to get the really bad eggs. By the way, many of the most successful small businesspeople I know only have high school educations; and we need more people in the trades (electrical, plumbing, etc), not more brainwashed collegians.
Why can't they? I have never in my life requested a blood or allergy test and had the doctor say "No, I won't let you."
