Of course it fails to advocate - which itself may have become a vice.
While I disagree with invoking child protection as a form of political blackmail, child protection is a legitimate concern. Several populations, of which children are one, are considered vulnerable to exploitation and legislation to reduce exploitation is legitimate.
The problem lies with the fragility of our political system. It is so fragile that debating the effectiveness of the legislation can be shut down with a handful of emotionally charged words. It is so fragile that seeking alternatives which don't impact fundamental rights is overlooked in the interests of expediency.
Of course, creating such rules of thumb is a symptom of the same disease. It is a tool to discourage debate rather than encourage it.
Genuine question because I never understand what people mean when they use that phrase: how is a right fundamental? Does the cold universe assign them to us or do a set of people agree such-and-such are fundamental. If the latter, were the same rights fundamental 20,000 years ago? (Because if they are fundamental, they should stretch back to early man… earlier than even 20,000 years ago)
The problem is they don't reduce it. It doesn't prevent the abuse and rape nor does it prevent the trade. They install mass surveillance that catches some idiots.
People should judge things like this based on the content and context of the legislation, not based on a 3 word summary of its justification. There’s your rule of thumb
