The whole thing is out of hand and it always is with these cases. Alfie Evans, Charlie Gard, a few more I'm sure I've forgotten... It's a many headed monster with these cases.
First off, parental rights versus parental responsibility. As a parent, you do not necessarily have your child's best interests at heart. You do not necessarily have the knowledge to make overarching decisions in some areas. It doesn't matter how much you love your child, or if you're doing it for 'them,' your child's best interests are what counts. Your child will always be your child but when you're blinkered by emotion, mental health, religion or whatever reason it may be, "it's my child," doesn't trump your child's best interests.
And not knowing what's best for your child doesn't make you a bad parent, just one who need's guidance. The bottom line is that you don't have to be abusive, a horrible person or insane for a court or third party to have to step in. However, a lot of this so called army seem to think loving your child equals having parental rights in any situation, as long as it's from a place of love.
Secondly, social media. I'm convinced that people love the grief circus and being grief vultures. It's like a club of social media tourism off the back of a dead or dying child. They make bracelets, post infographics, fundraise for a financial cause no one really seems certain of and make ridiculous suggestions like, "we can get Jeremy Kyle involved!" (I wish I was joking.)
I don't know why. Perhaps it's genuine outrage at the idea of parents only having responsibility, versus the perceived, indefinite rights some people believe they should have no matter what, because they're a parent. Perhaps it's the emotional volatility of the situation concerning dead and/or dying children. I'm also inclined to think it's somewhat to do with comprehension, ie, some people in these cases can genuinely read a hopeless medical summary and come away believing the child is still going to wake up and be completely fine.
I think a huge number of these people genuinely believe Archie and all the children in the aforementioned cases are being preyed on by doctors and that it's all big some conspiracy of the state trying to kill their child. When in reality, there are times when parents blinded by love- not hatred, abuse or bad parenting- need intervention from the state because loving your child does not equal knowing what is best for them.
