In the Best Interest of Whom?

When we become parents we take on certain responsibilities.
It can be overwhelming but if we truly desire to be a good parent, we face them all while loving our child.
So many times, as they move into thwe world, we see instances where our parental duties or responsibilities are called into question.
An example, if we do not vaccinate our children due to our beliefs.
It is a deeply personal issue and the parent may feel they have made the best decision for their child.
Yet, when faced with registering for school, those decisions are met with disapproval, intolerance and at times, a refusal to accept them and allow that child access to the school.
The parent deciding to not vaccinate may have done enough research to warrant questioning the side effects of vaccines and chose to not take that chance.
It is their right, is it not? Parent, it implies that they would be in the position to make such decisions regarding their own children, not anyone elses.
Please do not misunderstand, I am not advocating that any decision a parent makes must be in the best interest of the child.
Let's assume I am referring to decisions that do not include abuse, neglect, ignorance or apathy.
I am just using the vaccination hot button as a platform to illustrate that parental choices are not always just that-that our child's best interest is only served if it is a general consensus for the powers that be.
Certain institutions believe all vaccinations are necessary and worth any risk.
A parent may not agree.
Sop, who gets to decide? A child turns 17 and is now recognized as an adult in many ways, yet legally they are not,nor do most have the maturity to decide what may be best for themselves yet they are given the power to pull away from their own parent if they do not agree with the boundaries and the parent must now become a spectator to their own child's future.
BUT, make no mistake, you are responsible for all of their actions and safety, and welfare, only now it may be from a distance because now they can leave the home and not be held accountable for such a decision.
Am I rambling, probably because this touches on the heart (figuratively and literally) of the matter.
It affects me so personally that thinking becomes fuzzy and lines are now blurred because I feel like a Parent on the side line of my own child's life and not in any fair, sporting event.
I was prepared for the role that requires allowing my child to now face the world on their own, but not under these circumstance (or at just 17 years of age) and not given the concerns-this ill-advised placement of my child.
Because now, not only is that child allowed to stay in a very unsafe and unhealthy environment while I am helpless to intervene, but it is with the blessing of the SYSTEM.
My rights are where???
