So, should it be up to a parent to decide whether or not it's OK for their child to pose nude (providing the child wants to)?
If it could qualify as kiddie porn, which IMHO it could, then no, the parents should not be able to give consent. Unless the law is going to also find it acceptable for an underage girl to appear in Playboy, whose material could be considered art just as artsy pics of a naked 12 year old could be considered porn.
When a parent decides not to allow their child to receive medical care because of their religion, is that a personal liberties issue?
Well, I think that kids should have at least the protections that pets do. If you fail to get a very sick or injured dog vet care you would be arrested, so I don't see much logic in treating children differently, religion or not.
Where should a parent's right to make decisions for their child be questioned or even overridden by law?
When the child in in clear physical danger (either through abuse or neglect), when the child's educational needs are being severely neglected (parent won't send kid to school, won't make kid go to school, or home schools and does not teach the child the things that he/she needs to know, etc), or when it can be proven that the child is suffering severe mental abuse.
Parents make decisions for their children every day. When does it become the business of the government to step in and say, "Sorry, we'll make that decision for you."?
Well, the government does that a lot already and in many cases I believe it is justified. Just to give an example from my own family: My aunt and her estranged husband are crappy parents, there is just no other way to put it. Their kids always went to school dirty, etc. After a while, the boy stopped going to school and his mother failed to make him go to school, so they took him away and sent him to juvenile detention. In the meantime, my aunt and her husband stopped paying their rent and were evicted. My aunt and younger cousin, a girl, went to live in a homeless shelter. My aunt was kicked out of the shelter due to her bad behavior and my cousin was taken away because she had no place to live. Now, the only monthly expense my aunt even had was rent. My dad's other sister pays for her insurance and car payment. My dad and uncle were giving my aunt several hundred dollars a month to help with expenses and my aunt works full time. It's been *well* over a year since my cousin has been taken away and she still doesn't actually have a place to live--she lives in a room some lady's basement. While she did have my cousin in her custody (she was 8 or 9 at the time), my dad was always having to remind her to bathe my cousin and wash her clothes (when you can see the grease in a 8 year old's hair from across the room, you know there is a problem). As far as we know my aunt never hit my cousin, but she was verbally abusive. Once my dad and uncle bought my cousin a halloween costume. She was *so* excited to have her own costume that she was just beaming. The second she got it on (the kid hadn't even said a word) my aunt just started yelling at her "Now DON'T even THINK about getting any CANDY!" She believed that my cousin was retarded and referred to her as such in from of my cousin.
Although my aunt will say she wants the kids back, the social worker handling the case said that neither parent has done anything that the state requires to get their kids back in the nearly 2 years of them being in foster care. The case worker said that he has seen parents with much less resources then them move mountains to get their kids back, and he does not understand why my aunt and her husband aren't lifting a finger. not one person in our family thinks that they should have custody of those kids--they are much better off in therapeutic foster homes (which is where they are).
That situation, IMHO, is a good reason for the government to get involved.
The thing that is tough with kids is that so much of how they are raised has an effect on the rest of society. Kids allowed to miss school repeatedly that don't finish their education often end up as drains on society. Kids who are left to basically raise themselves often turn to gangs, etc.
