What caught my eye is the last two words in your post. And herein lies the heart of the discussion. What is age appropriate? To sum their children are NEVER an age to appreciate God knows what. I honestly believe children are smarter than we think. And while I will always concur that it is the parents obligation to decide what is age appropriate, you have to agree with me that many parents today have abdicated that responsibility to the internet where children are learning things the way they should never be allowed to.
Good post Fang, and to be honest, I sometimes struggle as a parent to balance the censorship of essential information with the need for education and enlightenment where my kids are concerned. Every family is different, but in most cases, children are all the same. They will all typically react emotionally (rather than intellectually) to things that are to them perhaps, scary, threatening, or simply downright confusing.
Knowing what information to provide at what point in a child's personal development in order to keep them safe from emotional harm is very tricky business for any parent, or adult for that matter, and is usually best decided by those that know them best. This being the case, it's hard for people to see organizations (as opposed to families) promote graphic symbols of contentious subjects which force their children into potentially emotionally damaging situations.
The sad part is that in many instances, those same adults are also incapable of dealing with those same contentious issues rationally and intellectually, and tend to react more emotionally than even a child might.
I actually have no issues with homosexuality or same-sex coupling, nor with many of the core concepts associated with the LGBT movement. Unfortunately, this movement has become a catch-all for many things that while not directly associated with the movement itself, are still deemed to be highly controversial in terms of behavior and/or lifestyle by the social majority, so when you do want to address the movement's core principles, you need to address all the rest too.
Therein lies the problem - the Rainbow Flag no longer represents what it was originally intended to, but rather a much broader, more complex, and nebulous scope of behavioral philosophy which many believe is definitely beyond the ability of younger minds to digest.
